arm64: optimize flush tlb kernel range
Currently the kernel TLBs is flushed page by page if the target
VA range is less than MAX_DVM_OPS * PAGE_SIZE, otherwise we'll
brutally issue a TLBI ALL.
But we could optimize it when CPU supports TLB range operations,
convert to use __flush_tlb_range_op() like other tlb range flush
to improve performance.
