cpu/atmega_common: Clean up & fix IRQ handling
...
At the end of an ISR, the ATmega code was doing an `thread_yield()` instead of
a `thread_yield_higher()`. This resulted in tests/isr_yield_higher failing.
Fixing this saves a few lines of code, some ROM, and solves the issue.

cpu/atmega_common: Stop using reserved names
...
Names with two leading underscores are reserved in any context of the c
standard, and thus must not be used. This ATmega platform used it however for
defining internal stuff. This commit fixes this.

cpu/atmega_common: Restructured code

platform specific low level part of the Neopixel driver.

atmega_common: provide CPU ID for every device
...
ATmega128RFA1/ATmega256RFR2 do not have a unique CPU ID.
Use the RC oscillator callibration byte as an impromptu CPU ID and rely
on bootlader constants present on all ATmega families for the remaining
bytes.
This way we can provide a faux CPU ID on all ATmega MCUs and typical hobbyists
with no access to JTAG adapters or high voltage programmer capable of writing
the user signature have a good chance that the CPU IDs of their device do not collide.

Makes AVR register definitions dependent on what avr-libc defines
