ARM: dts: rockchip: rv1106: disable usb2 gadget lpm

The Rockchip DWC3 controllers are LPM capable, but we find
that the 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 RV1106 platforms
with USB Gadget funcitons (UVC & UAC...), so we disable the
LPM capable by default.
