Add power-domains entry for smmu, so that the it is accessible as long
as the driver is active. Without this device shutdown is throwing the
below warning:
"[ 44.736348] arm-smmu-v3 36600000.smmu: failed to clear cr0"

Sorry for delay, I've been engulfed with various other pieces of work
and handling upstream has been quite slow.
Anyways, for this patch, queued up for 5.6, thanks!
