Subject: [PATCH v2 07/10] clk: qcom: Fix sc7180 gpucc parent data

The bindings file (qcom,gpucc.yaml) does not agree with the names we
use for input clocks.  Fix us.  This takes into account the changes in
the recent patch ("dt-bindings: clock: Fix qcom,gpucc bindings for
sdm845/sc7180/msm8998"), but even without that patch the names in the
driver were still not right.

Since we didn't add the "test" clock to the bindings (apparently it's
never used), kill it from the driver.  If someone has a use for it we
should add it to the bindings and bring it back.

Instead of updating the size of the array now that the test clock is
gone, switch to using the less error-prone ARRAY_SIZE.  Not sure why
it didn't always use that.
