> Most of the time the CPU should not be touching the GX domain on the
> GPU except for a very special use case when the CPU needs to force the
> GX headswitch off. Add the GX domain for that use case.  As part of
> this add a dummy enable function for the GX gdsc to simulate success
> so that the pm_runtime reference counting is correct.  This matches
> what was done in sdm845 in commit 85a3d920d30a ("clk: qcom: Add a
