clk: qcom: Add a driver for SM8750 GPU clocks

Support the graphics clock controller for SM8750 for Graphics SW
driver to use the clocks. GXCLKCTL (Graphics GX Clock Controller) is a
block dedicated to managing clocks for the GPU subsystem on GX power
domain. The GX clock controller driver manages only the GX GDSC and the
rest of the resources of the controller are managed by the firmware.

Update the compatible for Graphics GX Clock Controller for SM8750 as the
GX clock controller is a reuse of the Kaanapali driver.
