clk: qcom: gpucc-sc7180: fix clk_dis_wait being programmed for CX GDSC
...
The gdsc_init() function will rewrite the CLK_DIS_WAIT field while
registering the GDSC (writing the value 0x2 by default). This will
override the setting done in the driver's probe function.
Set cx_gdsc.clk_dis_wait_val to 8 to follow the intention of the probe
function.

clk: qcom: gpucc-sc7180: switch to parent_hws
...
Change several entries of parent_data to use parent_hws instead, which
results in slightly more ovbious code.

...
All gpucc drivers need this, so move it to common code instead of
duplicating it in every gpucc driver.

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 85a3d920d3tdas@codeaurora.org >

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

The test clock isn't in the bindings and apparently it's not used by
anyone upstream. Remove it.
