cpu/stm32: implement reset to bootloader
...
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.

This commit adds two new functions to the DMA peripheral code for the
stm32. The setup function allows for a one-time setup of peripheral
config. The prepare function does the per-transfer setup. This allows
for a single setup call during the peripheral lock step and a
per-transfer call to the prepare function.

cpu/atmega_common: Fixed irq_arch implementation
...
The inline assembly implementation was badly in need of improvement.
- irq_disable() took 2 CPU cycles more than needed
- The current interrupt state was stored in a temporary register and
afterwards copied to the target register, rather than storing it in the
target register right away
- The lower bits of the state were cleared (as they have no meaning for the
interrupt status), but the API purposely never required such things from
implementations.
- irq_restore() took 5 CPU cycles. This was reduced to 3 CPU cycles (or 2 CPU
cycles in the best case)

cpu/sam0_common/spi: move clk pin muxing into spi_acquire / spi_release
...
When the SPI peripheral is disabled, the output lines will become HIGH-Z.
If the clk pin is not pulled HIGH or LOW, connected SPI slaves will start drawing current expectedly.

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.

cpu/stm32_common: fix issue while clearing EXTI->PR reg
...
Since the "EXTI->PR" is an "rc_w1" type of register, we need to be
careful when clearing our interrupt flag in the register. When there
are multiple interrupt flags set in the register, the "|=" operation
will mistakenly clear all pending interrupts instead of just ours.

cpu/atmega_common/periph/pwm: Minor fix & cleanup
...
- On pwm_poweron, the PWM resolution was not restored. (A custom resolution was
only usable if, PWM channel 0 is not used. That configuration is not common,
so this bug was likely never triggered)
- Disabled a work around to prevent flickering:
- Previously, PWM was disconnected on level 0% and 100%
- This increases the run time of `pwm_set()`
- It prevents using the PWM for wave form generation via DDS, as the wave
noticeably jumps when reaching 0% or 100%
- Slightly reduces memory requirements: 2 Bytes of RAM, 112 Bytes of ROM
- Tested with avr-gcc 9.2.0 and LTO enabled

We do not manipulate the CPSR register outside of irq_%, so we can just
restore it's previous value and don't have to fiddle with the IRQ MASK bit.

- The higher values for default stack size of `cpu_conf.h` in
`cpu/atmega_common` results in three tests no longer fitting the available RAM
==> Updated the Makefile.ci to skip linking of those tests for the Arduino
