[PATCH 2/3] mips: use PAGE_SIZE in assembly instead of _PAGE_SIZE.

[Tim Abbott <tabbott@xxxxxxxxxxx>]

From: Nelson Elhage <nelhage@xxxxxxxxxxx>

Now that PAGE_SIZE is available to assembly directly, there is no need
to separately expose it as _PAGE_SIZE through asm-offsets.

In addition, remove _PAGE_SHIFT from asm-offsets, since it was never
needed, and is not used anywhere.
