[PATCH v13 1/5] dt-bindings: phy: qcom,sc8280xp-qmp-pcie-phy: Update pcie phy bindings for qcs8300

The gcc_aux_clk is not required by the PCIe PHY on qcs8300 and is not
specified in the device tree node. Hence, move the qcs8300 phy
compatibility entry into the list of PHYs that require six clocks.

Removed the phy_aux clock from the PCIe PHY binding as it is no longer
used by any instance.
