Subject: [PATCH 02/15] dt-bindings: clock: qcom,dispcc-sm6125: Remove
 unused GCC_DISP_AHB_CLK

The downsteam driver for dispcc only ever gets and puts this clock
without ever using it in the clocktree; this unnecessary workaround was
never ported to mainline, hence the driver doesn't consume this clock
and shouldn't be required by the bindings.

Fixes: 8397c9c0c26b ("dt-bindings: clock: add QCOM SM6125 display clock bindings")
