csky: Enable defer flush_dcache_page for abiv2 cpus (807/810/860) Instead of flushing cache per update_mmu_cache() called, we use flush_dcache_page to reduce the frequency of flashing the cache. As abiv2 cpus are all PIPT for icache & dcache, we needn't handle dcache aliasing problem. But their icache can't snoop dcache, so we still need sync_icache_dcache in update_mmu_cache().
