69858916c7 boards: enable CAN bus on nucleo-f446re & nucleo-f446ze 
Changed the pinout for the CAN bus:
CAN RX: PB8
CAN TX: PB9

And added periph_can to FEATURES_PROVIDED and to Kconfig files

cpu/stm32/periph_eth: Optimize / fix flush 
- Added missing wait for TX flush
- Grouped access to the same registers of the Ethernet PHY to reduce accesses.
  (The compiler won't optimize accesses to `volatile`, as defined in the C
  standard.)

cpu/stm32/periph_eth: Cleanup & fix DMA descriptor 
- Add missing `volatile` to DMA descriptor, as memory is also accessed by the
  DMA without knowledge of the compiler
- Dropped `__attribute__((packed))` from DMA descriptor
    - The DMA descriptor fields need to be aligned on word boundries to
      properly function
    - The compiler can now more efficiently access the fields (safes ~300 B ROM)
- Moved the DMA descriptor struct and the flags to `periph_cpu.h`
    - This allows Doxygen documentation being build for it
    - Those types and fields are needed for a future PTP implementation
- 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

7269dc4e3a cpu/sam0_common: i2c: allow arbitrary I2C frequencies 
The Atmel I2C peripheral supports arbitrary I2C frequencies.
Since the `i2c_speed_t` enum just encodes the raw frequency values,
we can just use them in the peripheral definition.

We just have to remove the switch-case block that will generate an error
for values outside of `i2c_speed_t`.

47e2885f80 cpu/native: async_read: add native_async_read_add_int_handler() 
fcntl(fd, F_SETOWN, getpid()); doesn't seem to work on Linux
to get generate a signal when an event on the GPIO fd occurs.

So fall back to the same method as on OS X and call poll() in
a child process.

a274ea45fc cpu/native: async_read: rewrite select() call to poll() 
select() can not listen to POLLPRI events which are used by the
Kernel's GPIO API.

In preparation for that, rewrite async_read() to use poll() instead
of select().

cortexm_common: Clear PendSV request after idle sleep 
The PendSV interrupt is used to request a scheduling operation. An
interrupt during the idle sleep can re-request the PendSV interrupt,
while the PendSV is still busy scheduling the next thread. This clears
the request after sleep to prevent triggering an extra PendSV interrupt
after the current PendSV handler finished.
