MIPS: IP27: Remove pfn_t.
In the Linux kernel traditionally pfns are represented by an unsigned long. However a few bits of the SGI IP27 platform code that were ported from IRIX are using pfn_t for historic reasons. This is conflicting with KVM's use of pfn_t. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
