Also, convert them to resource_size_t (which is unsigned long
on 64-bit, so it's not a change there).
We will be using these on fsl 32b to indicate the start and size
address of memory that the pci controller can actually reach - this
is needed to determine if an address requires bounce buffering. For
now, initialize them to a standard value; in the near future, the
value will be calculated based on how the inbound windows are
programmed.
