Mark Brown d7b77a0d56 arm64/sme: Restore SMCR_EL1.EZT0 on exit from suspend ...

The fields in SMCR_EL1 reset to an architecturally UNKNOWN value. Since we
do not otherwise manage the traps configured in this register at runtime we
need to reconfigure them after a suspend in case nothing else was kind
enough to preserve them for us. Do so for SMCR_EL1.EZT0.
