v5 cover Add DT bindings and DT nodes for USB in SC7280

This series includes usb controller and phy binding updates for SC7280 SoC and DT chnages for SC7280 SoC and SC7280 IDP board.

changes in v5:
Added patch for usb3-dp phy bindings for SC7280.
Changed qmp usb phy to usb dp phy combo node as per Stephen's comments. Changed dwc to usb and added SC7280 compatible as per Bjorn's comments.

changes in v4:
changed usb3-phy to lanes in qmp phy node as it was causing probe failure.

changes in v3:
Moved the board specific changes to separate patch. Addressed comments from Matthias in v2.

changes in v2:
Dropped dt bindings patches as they are already merged in linux-next. Addressed comments from Matthias in v1.

which looks like genirq code is complaining that the type is different than what it is configured for. Are these trigger flags correct? If so, then there' some sort of bug in the pdc driver.

which looks like genirq code is complaining that the type is different than what it is configured for. Are these trigger flags correct? If so, then there' some sort of bug in the pdc driver.

I should be using  IRQ_TYPE_LEVEL_HIGH. Will correct in next version.
