usb: dwc3: gadget: disable lpm for rockchip platform

Browse Source 
The rockchip DWC3 controllers are LPM capable, but we find
that UVC function compatibility issue on some Windows PCs
if enable LPM capable. And refer to the Logitech USB Cameras,
they're usually disable LPM capable. Considering that the
benefit form LPM capable is insignificant on Rochip platforms,
so we disable the LPM capable by default.
