iommu/arm-smmu: Make fault triggering more reliable
We're currently disabling clocks/power immediately after writing to
FSRRESTORE, but if the fault is not handled before we disable the
clocks/power then the fault could be lost. Add a 1-second sleep after
writing to FSRRESTORE to give the interrupt time to fire before turning
clocks/power back off.
