powerpc/fsl-booke: Fix mapping functions to use phys_addr_t

Fixed v_mapped_by_tlbcam() and p_mapped_by_tlbcam() to use phys_addr_t instead of unsigned long. In 36-bit physical mode we really need these functions to deal with phys_addr_t when trying to match a physical address or when returning one. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
