The USB controller on sm6375 doesn't retain its state when the system
goes into low power state and the GDSCs are turned off.
This can be observed by the USB connection not coming back alive after
putting the device into suspend, essentially breaking USB.
Work around this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.
This change should be reverted when a proper suspend sequence is
implemented in the USB drivers.
