PPC: Fix compile with profiling enabled

When using profiling, we rely on profile_getclock() being available
at our disposal. Somehow that function got moved from an indirect
include we used to have in translate-init.c, so that we were now
left not properly compiling anymore.

Add an explicit include to timer.h which defines profile_getclock,
so that we can compile again.
