PCI: fix ram_address() to use phys_addr_t

Since it handles physical address it should really be this.

It's not like many drivers actually used it anyway. It shouldn't harm
compatibility, drivers calling it with only 32bit would leave garbage in
the higher bits but since on x86 it's a noop anyway, it would end up in
the MSB register tha's ignored because it expects a 32bit result.
