[POWERPC] Add memory regions to the kcore list for 32-bit machines
The entries are only 32-bit, so restrict the virtual address to stay
below 0xffff_ffff. With KERNELBASE set to 0xc000_0000, this in effect
restricts access to the first 1GB of real memory.
Make setup_kcore conditional on CONFIG_PROC_KCORE for both 32/64.
