Catalin Marinas 7e1c1db08e arm64: Implement pmdp_set_access_flags() for hardware AF/DBM ...

commit 282aa7051b upstream.

The update to the accessed or dirty states for block mappings must be
done atomically on hardware with support for automatic AF/DBM. The
ptep_set_access_flags() function has been fixed as part of commit
66dbd6e61a ("arm64: Implement ptep_set_access_flags() for hardware
AF/DBM"). This patch brings pmdp_set_access_flags() in line with the pte
counterpart.
