mips: fix r3k_cache_init build regression

My earlier patch removed __weak function declarations that used to be
turned into wild branches by the linker, instead causing a link failure
when the called functions are unavailable:

mips-linux-ld: arch/mips/mm/cache.o: in function `cpu_cache_init':
cache.c:(.text+0x670): undefined reference to `r3k_cache_init'

The __weak method seems suboptimal, so rather than putting that back, make
the function calls conditional on the Kconfig symbol that controls the
compilation.
