Please remove "ti,omap-pcie" for now, you can add it later whenever you add
dpll settings for pcie.
Also, please change the newly added compatible strings to
"ti,phy-pipe3-usb3" and "ti,phy-pipe3-sata"
Also you need to rearrange the patches so that the DT binding document is first
moded from usb/ to phy/ and then the change is done for pipe3.
