sh: avoid multiple definition errors with cache funcs
Recent builds for SH4 boards fail with a lot of errors like:
cmd_mem.o: In function 'dcache_invalid_range':
include/asm/cache.h:25: multiple definition of 'dcache_invalid_range'
include/asm/cache.h:25: first defined here
This is due to the funcs being defined in the header, but not static
or inline or extern. So move them to the sh4-specific cache.c file.
