[PATCH v3 1/3] dt-bindings: phy: qcom, hdmi-phy-qmp: add clock-cells and XO clock

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

As the QMP HDMI PHY is a clock provider, add constant #clock-cells
property. For the compatibility with older DTs the property is not
marked as required. Also add the XO clock to the list of the clocks used
by the driver.
