Way too much.

The first step is done.  I moved the bat initialization, trap vector
setup, interrupt installer, the dump routine, the vm startup code and
a few others to arch/powerpc/mpc6xx/mpc6xx_machdep.c

Along way, I moved the syscall code (and child_return) out of trap.c
into syscall.c which is common across both mpc6xx and ibm4xx.

I've placed the rest of the diffs to the rest of the ppc ports at
ftp://ftp.netbsd.org/pub/incoming/matt/ppc.diffs

I'm planning on changing the bat initialization calling args.
