powerpc/signal: Move inline functions in signal.h

Browse Source 
To really be inlined, the functions need to be defined in the
same C file as the caller, or in an included header.

Move functions defined inline from signal .c in signal.h

Fixes: 3dd4eb83a9 ("powerpc: move common register copy functions from signal_32.c to signal.c")
