powerpc: PTRACE_PEEKUSR/PTRACE_POKEUSER of FPR registers in little endian builds

Browse source

FPRs overlap the high 64bits of the first 32 VSX registers. The
ptrace FP read/write code assumes big endian ordering and grabs
the lowest 64 bits.

Fix this by using the TS_FPR macro which does the right thing.
