...which is a fairly standard thing to do for a rudimentary runtime PM
support on platforms that use power domains.

This will likely (almost surely) break other platforms.

Without a runtime PM get call, the power domain that this device is in
could be powered off without this driver ever knowing about it, causing
a crash as soon as the driver is used after the domain is turned off.
