For all currently supported platforms `unsigned long` is 32 bit in width. But
better use `uint32_t` to be safe.

cpu/stm32: Fix reception bug in periph_eth
...
The reception code hands RX DMA descriptors back to the DMA right after its
contents were copied into the network stack internal buffer. This increases
the odds that the DMA never runs out of DMA descriptors to fill, even under
high load. However, the loop fetching the Ethernet frame stops to iterate at the
end of the frame. If the DMA used one more descriptor to store the FCS, this
was not returned back to the DMA. This commit fixes it.

Expose the auto-negotiation feature of the Ethernet device via the
pseudo-module stm32_eth_auto. With this enabled, the static speed configuration
set in the boards periph_conf.h will only be used if the PHY lacks
auto-negotiation capabilities - which is unlikely to ever happen.

cpu/stm32: Fix/cleanup periph_eth
...
The methods to read from / write to MII registers had an address argument to
allow specifying the PHY to communicate with. However, only a single PHY is
available on all boards supported and the driver is not able to operate with
multiple PHYs anyway - thus, drop this parameter for ease of use.
This fixes a bug in the _get_link_status() function, which used hard coded the
address 0; which might not be correct for all boards.

Using the TER bit in the TX descriptors when only using a single descriptor for
sending triggered a hardware bug. Thus, stop using the TER bit and store the
currently active TX descriptor in RAM instead.

driver/stm32_eth: Integrate into periph_eth
...
The stm32_eth driver was build on top of the internal API periph_eth, which
was unused anywhere. (Additionally, with two obscure exceptions, no functions
where declared in headers, making them pretty hard to use anyway.)
The separation of the driver into two layers incurs overhead, but does not
result in cleaner structure or reuse of code. Thus, this artificial separation
was dropped.

cpu/stm32/periph_eth: zero-copy TX (-6 KiB RAM)
...
The Ethernet DMA is capable of collecting a frame from multiple chunks, just
like the send function of the netdev interface passes. The send function was
rewritten to just set up the Ethernet DMA up to collect the outgoing frame
while sending. As a result, the send function blocks until the frame is
sent to keep control over the buffers.
This frees 6 KiB of RAM previously used for TX buffers.

cpu/stm32/periph_eth: configurable buffer size
...
1. Move buffer configuration from boards to cpu/stm32
2. Allow overwriting buffer configuration
- If the default configuration ever needs touching, this will be due to a
use case and should be done by the application rather than the board
3. Reduce default RX buffer size
- Now that handling of frames split up into multiple DMA descriptors works,
we can make use of this
Note: With the significantly smaller RX buffers the driver will now perform
much worse when receiving data at maximum throughput. But as long as frames
are small (which is to be expected for IoT or boarder gateway scenarios) the
performance should not be affected.

cpu/stm32/periph_eth: Fix RX logic
...
If any incoming frame is bigger than a single DMA buffer, the Ethernet DMA will
split the content and use multiple DMA buffers instead. But only the DMA
descriptor of the last Ethernet frame segment will contain the frame length.
Previously, the frame length calculation, reassembly of the frame, and the
freeing of DMA descriptors was completely broken and only worked in case the
received frame was small enough to fit into one DMA buffer. This is now fixed,
so that smaller DMA buffers can safely be used now.
Additionally the interface was simplified: Previously two receive flavors were
implemented, with only one ever being used. None of those function was
public due to missing declarations in headers. The unused interface was
dropped and the remaining was streamlined to better fit the use case.

cpu/stm32: implement periph_timer_periodic
...
Seems like the Interrupt flag for a Capture/Compare channel gets set when
- the CC-value is reached
- the timer resets before the CC value is reached.
We only want the first event and ignore the second one. Unfortunately I did
not find a way to disable the second event type, so it is filtered in software.
That is we need to
- ignore the CC-interrupts when the COUNT register register is reset
- ignore the CC-interrupts > TOP value/ARR (auto-reload register)

- Moved the DMA descriptor struct and the flags to `periph_cpu.h`

- Renamed DMA descriptor flags
- They now reflect to which field in the DMA descriptor they refer to, so
that confusion is avoided
- Added documentation to the DMA descriptor and the corresponding flags

cpu/stm32: Fix uart_init()
...
- Make use of the fact that gpio_init_af() does not need prior call to
gpio_init() for all STM32 families anymore and drop call to gpio_init()
- Initialize the UART periph first, before initializing the pins
- While uninitialized, the UART periph will send signal LOW to TXD. This
results in a start bit being picked up by the other side.
- Instead, we do not connect the UART periph to the pins until it is
initialized, so that the TXD level will already be HIGH when the pins
are attached.
- This results in no more garbage being send during initialization

The STM32 line of microcontrollers comes with a bootloader in the ROM.
It provides the option to flash the device firmware in DFU mode (USB)
or via UART or SPI.
To enter the bootloader we have to jump to a specific address in memory,
but before reset the CPU to make sure the system is in a known state.
This enables us to use the usb_board_reset module on all STM32 platforms.

cpu/stm32: filter availability of RNG by CPU not by board.
...
The old limitation is not valid anymore, we can evaluate $(CPU_MODEL)
here directly.
The output of
make -C tests/periph_hwrng info-boards-supported | wc -w
remains the same.

cpu/stm32: don't include usbdev_stm32.h in periph_cpu_common.h
...
`usbdev_stm32.h` will pull in `usb.h` which causes an error if
`USB_H_USER_IS_RIOT_INTERNAL` is not set.
Turns out this include is not needed, so just drop it.

stm32/dma: Remove superfluous asserts from DMA hot path
...
This commit removes a number of assert statements that should already
have been hit before. This is the reason that the assert in the
acquire function is left.
