pcmcia: Use phys_addr_t for physical addresses

Physical addresses are currently represented as int or long types.
However, this does not work for processors like the PPC440EPx, which
is a 32-bit processor with a 36-bit address space.  This patch uses
the phys_addr_t type, which correctly holds a 36-bit address on
this processor.
