[MIPS] Cleanup TO_PHYS_MASK definition
No point in adding yet another #ifdef for Loongson since all this mask is being used for is converting an XKPHYS address into a physical address anyway. So replace all definitions by one with the highest architectural possible value. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
