ARMv7: Use lazy cache flushing if hardware broadcasts cache operations

ARMv7 processors like Cortex-A9 broadcast the cache maintenance
operations in hardware. The patch adds the CPU ID checks for such
feature and allows the flush_dcache_page/update_mmu_cache pair to work
in lazy flushing mode similar to the UP case.
