Subject: [PATCH 02/10] clk: qcom: ipq5332: Add separate clocks for PCIe and USB for Combo PHY

Qualcomm IPQ5332 has a combo PHY for PCIe and USB. Either one of the
interface (PCIe/USB) can use this combo PHY and the PHY drivers are
different for PCIe and USB. Hence separate the PCIe and USB pipe clock
source from DT, and individual driver node can be used as a clock source
separately in the gcc. Add separate enum for PCIe and USB pipe clock and
change the parent in corresponding structures.
