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.
v3: Fix some small changes in $subject
    address the input from Neil
    fix the vialab device tree binding as per Krzysztof inputs.

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.
