powerpc: merge idle_power4.S and trapc.s
Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.
Merge ppc64 traps.c into powerpc traps.c:
use ppc64 versions of exception routine names
(as they don't have StudlyCaps)
make all the versions if die() have the same
prototype
