It would be helpful for 36-bit 4xx core implementations (440gp/440gx)
if the paddr used the phys_addr_t typedef so we could store a
native 64-bit address.

It would appear to me that one would expect to be able to do
the following:

	ioremap(get_ocp_paddr(<type>, <num>), <size>);

Is that the intention?
