[PATCH 18/20] mips: hide conditionally unused functions

Arnd Bergmann

A couple of functions are defined unconditionally but have a
conditional declaration:

arch/mips/mm/tlb-r4k.c:461:12: error: no previous prototype for 'add_temporary_entry' [-Werror=missing-prototypes]
arch/mips/mm/pgtable-64.c:92:7: error: no previous prototype for 'mk_pmd' [-Werror=missing-prototypes]
arch/mips/mm/pgtable-64.c:101:6: error: no previous prototype for 'set_pmd_at' [-Werror=missing-prototypes]

Since there are no callers in these configurations, add the same #ifdef
checks around the definitions.
