Johan Hovold 9410fb9401 clk: qcom: gcc-sc8280xp: use phy-mux clock for PCIe ...

Use the new phy-mux clock implementation for the PCIe pipe clock muxes
so that the pipe clock source is set to the QMP PHY PLL when the
downstream pipe clock is enabled and restored to the always-on XO when
it is again disabled.

This is needed to prevent the corresponding GDSC from hanging when
enabling or disabling the PCIe power domain, something which requires a
ticking source.
