usb: dwc2: Disable power down feature on Rockchip SoCs

Browse Source 
Power down feature of DWC2 module integrated in Rockchip SoCs doesn't work
properly or needs some additional handling in PHY or SoC glue layer, so
disable it for now. Without disabling power down, DWC2 sporadically cannot
detect USB disconnect.
