arm64/mm: convert ptep_clear() to ptep_get_and_clear()
ptep_clear() is a generic wrapper around the arch-implemented
ptep_get_and_clear(). We are about to convert ptep_get_and_clear() into a
public version and private version (__ptep_get_and_clear()) to support the
transparent contpte work. We won't have a private version of ptep_clear()
so let's convert it to directly call ptep_get_and_clear().
