ppc: Adjust isa_io_base for ppc64
To avoid cast warnings, use a 64-bit ISA I/O base on ppc64.
v3:
* Adjust unix target, pointed out by Blue.
Unify ppc and sparc64, using unsigned long instead of uintptr_t.
It is initialized from pci_arch_t, which uses unsigned long.
* Update other ppc targets, pointed out by Blue.
v2:
Initial.
