[v2,0/9] Used onboard HUB to reset and add power to hub

Message

Amlogic board use gpio-hog to reset the USB hub.
so using onboard hub we could reset the USB hub and
also enable power to the USB hub.

v2: Odroid C1 / C2 : usb hub reset working as expected.
    Odroid N2 : dropped usb hub changes, since my board USB hub
		is hitting regression.
    Odroid C4 : Fix the device tree binding and used peer-hub for
		usb2.0 and usb3.0 hub.

v1: Odroid C1 / C2 : were not working as expected.
    Odroid N2 : used single USB 3.0 hub reset.
    Odroid C4 : used single USB 3.0 hub reset.

Any inputs for these changes ?

Thanks
