This commits adds a common type for the block writes to the flash of the
stm32. Depending on the family, the type has a different size. This
allows the removal of a number of ifdefs to track the differences
between families, simplifying the flashpage code

Cortex-M4 core headers.

As stm32mp1 family accesses gpio pins with a different
offset than other stm32, create a specific macro.

* Setup i2c speed to I2C_SPEED_LOW by default
* enable i2c_write_regs() function.
* i2c frequency needs to be specified into board periph_conf.h

Default values were wrong for WB when using HSE 32MHz as PLL input source
Default PLL input source was wrong when not using HSE and the board
provides an HSE
This adds a placeholder define for when the DMA peripheral available on
the MCU doesn't support channel/trigger filtering. This is the case on
the stm32f1 and stm32f3 family.
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.
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.
