MIPS: allow systems to skip loads during cache init
Current MIPS systems do not require that loads be performed to force the parity of cache lines, a simple invalidate by clearing the tag for each line will suffice. Thus this patch makes the loads & subsequent second invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD option, and defines that for existing mips32 targets. Exceptions are malta where this is known to be unnecessary, and qemu-mips where caches are not implemented.
