Changes in V2:
- Picked up the R-b tag
- Did not convert the clock IDs to numerical values as the clock
header (dependent patch) is merged in latest rc1.

+ The QMP PHY controller supports physical layer functionality for a number of
+ controllers on Qualcomm chipsets, such as, PCIe, UFS, and USB.

Could you please reorder the clocks in the following way:
- aux
- cfg_ahb
- pipe
- .. the rest
This will allow us to use this schema for other IPQ QMP PCIe PHYs.
