[POWERPC] Fix powermac late initcall to only run on powermac
Current ppc64_defconfig kernel fails to boot on iSeries, dying with:
Unable to handle kernel paging request for data at address 0x00000000
Faulting instruction address: 0xc00000000071b258
Oops: Kernel access of bad area, sig: 11 [#1]
SMP NR_CPUS=32 iSeries

Kernel panic - not syncing: Attempted to kill init!
This happens because some powermac code unconditionally sets
ppc_md.progress to NULL. This patch makes sure the powermac late
initcall is only run on powermac machines.
