MT2701 with a variety of devices in host mode and with the
f_mass gadget driver in peripheral mode, plugging otg cables
in/out a lot of times in all possible imaginable plug orders.

followed by "mediatek,mtk-musb"
2. Add usb connector child node
changes of DTS:
1. Add usb connector child node
changes of driver suggested by Bin:
