[PATCH] arm64: dts: qcom: glymur: Drop RPMh CXO clocks from QMP PHYs

[Abel Vesa]

On Glymur, all QMP PHYs except the one used by USB SS0 take their
reference clock from the TCSR clock controller. Since these TCSR clocks
already derive from RPMH_CXO_CLK as their sole parent, there is no need
to provide an extra `clkref` clock to the PHY nodes.

Drop the extra RPMh CXO clock inputs and use the TCSR clocks as the PHY
reference clocks instead.

This also fixes the devicetree schema validation, as the bindings do not
allow a separate `clkref` clock.

Thanks for fixing this, appreciated.

Bjorn,
That's a fix for v7.1-rcX, so please consider it for the fixes for
current (v7.1) release.

Best regards,
Krzysztof
