[PATCH] powerpc: some prom.c cleanups

On !CONFIG_PPC_MULTIPLATFORM _machine is defined as 0.  This is ok, but
we can't assign a value to _machine then.

We may not have CONFIG_PCI available, so only build in support for
find_parent_pci_resource(), request_OF_resource(), release_OF_resource()
if PCI is enabled.  This is probably not the long term fix but works out
for now.

Make reg_property64 contain 64-bit elements on a 32-bit machine.

Mark the deprecated prom.c functions as __deprecated.
