[PATCH v6 09/18] arm64/mm: Convert ptep_clear() to ptep_get_and_clear()

[Ryan Roberts]

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().
