Revert "armv8: enable HAFDBS for other ELx when FEAT_HAFDBS is present"
This reverts commit c1da6fdb5c239b432440721772d993e63cfdeb20. This is
part of a series trying to make use of the arm64 hardware features for
tracking dirty pages. Unfortunately this series causes problems for the
AC5/AC5X SoCs. Having exhausted other options the consensus seems to be
reverting this series is the best course of action.
