Fix a sh4-randconfig build failure which has the following splat:
arch/sh/mm/cache-sh4.c:99:17: error: 'cached_to_uncached' undeclared (first use in this function)
arch/sh/mm/cache-sh4.c:192:2: error: implicit declaration of function 'cpu_context' [-Werror=implicit-function-declaration]
These errors are caused by missing dependencies on UNCACHED_MAPPING and MMU.

Selecting MMU is never the correct solution, as it's a platform feature.
Making something depend on MMU is something different, but I doubt
SH4 can only work with a MMU, cfr. the "if MMU" in the line above.
Back to the drawing board...
