With a 64K page size flush with start and end value as below
(start, end) = (721f680d0000, 721f680e0000) results in
(hstart, hend) = (721f68200000, 721f68000000)
Avoid doing a __tlbie_va_range with the wrong hstart and hend value in this
case.
__tlbie_va_range will skip the actual tlbie operation for start > end.
But we still end up doing the tlbie fixup.
