[PATCH] usb: dwc2: disable power_down on Amlogic devices

[Christian Hewitt]

USB devices work when connected to Amlogic GXBB hardware before power
on, but not when connected after boot (hotplugged). With this patch
hotplugging works again. This change was copied from the Rockchip
patch here: (https://marc.info/?l=linux-usb&m=153205711616460&w=2)
