powerpc/signal: Remove get_clean_sp()

Browse source

get_clean_sp() is only used once in kernel/signal.c .

GCC is smart enough to see that x & 0xffffffff is a nop
calculation on PPC32, no need of a special PPC32 trivial version.

Include the logic from the PPC64 version of get_clean_sp() directly
in get_sigframe().
