Revert "MIPS: Fix PAGE_MASK definition"

commit 800dc4f49cc002879e1e5e6b79926f86b60528e6 upstream.

This reverts commit 22b14523994588279ae9c5ccfe64073c1e5b3c00.

It was originally sent in an earlier revision of the pfn_t patchset.
Besides being broken, the warning is also fixed by PFN_FLAGS_MASK
casting the PAGE_MASK to an unsigned long.
