cpu/atmega_common: Drop legacy include
...
Drop `#include "irq.h"` in `cpu.h`, which was there for a legacy work around.
A bunch of missing includes of `irq.h` materialized due to this and were
fixed.

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.
