powerpc: Merge time.c and asm/time.h.
We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c. This also makes an
asm-powerpc/rtc.h.
