I intended to, with "reg is used here to store a physical register address",
but probably didn't make it sufficiently clear. Before the advent of PAE and
phys_addr_t, unsigned long was used to store physical addresses.
We could indeed use u32, as the PFC regs are (currently) inside the 32-bit
part of the address space.
