76f6362292 cpu/fe310: Don't register __libc_fini_array with atexit 
Picolibc makes atexit state per-thread instead of global, so we can't
register destructors with atexit in a non-thread context as we won't
have any TLS space initialized.

saml1x: Remove MPU feature 
The MPU on the cortex-m23 has some differences with the MPU on the older
cortex-m devices. It is not implemented in the cortex-m MPU driver. This
removes the available feature as it gives a false sense of security by
advertising the feature, but implementing it with noop's

stm32: Add define for when DMA channel selection is not supported 
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.

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.
