0638226dd0 clk: qcom: add common gdsc_gx_do_nothing_enable for gpucc drivers 
All gpucc drivers need this, so move it to common code instead of
duplicating it in every gpucc driver.

1a6151128c clk: qcom: gpucc: Add support for GX GDSC for SC7180 
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
dummy enable function for GX gdsc").

72de7a19ef clk: qcom: Use ARRAY_SIZE in gpucc-sc7180 for parent clocks 
It's nicer to use ARRAY_SIZE instead of hardcoding.  Had we always
been doing this it would have prevented a previous bug.  See commit
74c31ff9c84a ("clk: qcom: gpu_cc_gmu_clk_src has 5 parents, not 6").

39c064a0e6 clk: qcom: Get rid of the test clock for gpucc-sc7180 
The test clock isn't in the bindings and apparently it's not used by
anyone upstream.  Remove it.

745ff069a4 clk: qcom: Add graphics clock controller driver for SC7180 
Add support for the graphics clock controller found on SC7180
based devices. This would allow graphics drivers to probe and
control their clocks.
