When the kernel gained support for FEAT_FPMR and FEAT_SME2,
corresponding support was not added to the boot-wrapper. Both of these
features require some (trivial) enablement to avoid traps being taken to
EL3 durung normal operation.
These patches add the missing support to the boot-wrapper.
The first two patches were prviously posted as part of an earlier
series:

I've updated their commit messages for clarity, but I have made no
functional changes.
Mark.
