powerpc/pmac: Don't register pmac PIC syscore ops when HW not present 

The Apple custom PIC only exist in some earlier machine models,
anything with an MPIC will crash on suspend if we register those
syscore ops unconditionally.

This is a regression caused by commit f5a592f7d7 ("PM / PowerPC: Use
struct syscore_ops instead of sysdevs for PM")
