"usb: dwc3: resume phy during gadget initialization on recent cores" breaks phy suspend

Commit "usb: dwc3: resume phy during gadget initialization on recent
cores" breaks phy suspend on cores newer than 1.94a. The core will
still operate, but the power savings provided by phy suspend are lost.

Pratyush, did you see an actual problem caused by the original code?
If so, then you need to reenable phy suspend at some point after
initialization to restore the correct behavior on newer cores.
