[MIPS] Fix swap entry for MIPS32 36-bit physical address
With 64-bit physical address enabled, 'swapon' was causing kernel oops on
Alchemy CPUs (MIPS32) because of the swap entry type field corrupting the
_PAGE_FILE bit in 'pte_low' field. So, switch to storing the swap entry in
'pte_high' field using all its bits except _PAGE_GLOBAL and _PAGE_VALID which
gives 25 bits for the swap entry offset.
