clk: qcom: gcc-sm6350: Update the .pwrsts for usb gdscs

The USB controllers on sm6350 do not retain the 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.

Fix this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.
