Supports TLB range operations when flush tlb kernel range.

v3:
- add helper to check maximum number of TLBI operations to avoid
  duplicate code in flush_tlb_kernel_range(), suggested by Anshuman
v2:
- address Catalin's comments and use __flush_tlb_range_op() directly

Kefeng Wang (2):
  arm64: tlbflush: add __flush_tlb_range_limit_excess()
  arm64: optimize flush tlb kernel range
