[PATCH 07/20] mips: move build_tlb_refill_handler() prototype

Instead of having a declaration for each caller, have one that is shared
with the function definition, which avoids a warning:

arch/mips/mm/tlbex.c:2547:6: error: no previous prototype for 'build_tlb_refill_handler' [-Werror=missing-prototypes]
