generic: make PFN_PHYS explicitly return phys_addr_t
PFN_PHYS, as its name suggests, turns a pfn into a physical address.
However, it is a macro which just operates on its argument without
modifying its type. pfns are typed unsigned long, but an unsigned
long may not be long enough to hold a physical address (32-bit systems
with more than 32 bits of physcial address).
Make sure we cast to phys_addr_t to return a complete result.
