From: Nickolay Goppen <setotau@xxxxxxxxx>
For the proper functioning of SMMUs related to the audio/compute DSPs,
it makes sense that the clocks and power domains they rely on for
communication should be online.
Add the vote clocks & GDSCs that, when enabled, ensure all such
requirements are met, through various internal mechanisms.
