MIPS: Loongson-3: Set cache flush handlers to cache_noop
Loongson-3 maintains cache coherency by hardware, this means:
1) It's icache is coherent with dcache.
2) It's dcaches don't alias (maybe depend on PAGE_SIZE).
3) It maintains cache coherency across cores (and for DMA).
So we can skip most cache flush operations by setting relevant handlers
to `cache_noop' in `r4k_cache_init'.
