compiler_abstraction.h does not have __FALLTHROUGH

[Vincent Belaïche]

Hello Nordic experts,

AFAIK, in the compiler_abstraction.h there is not such thing as:

#define __FALLTHROUGH __attribute__ ((fallthrough))

IMHO this is missing…

That seems to be a GCC-specific thing.

All it does is suppress the -Wimplicit-fallthrough warning:

So it isn't really like any of the other things currently in compiler_abstraction.h
