[PATCH v2 2/9] ARM: dts: amlogic: Used onboard usb hub reset to enable usb hub

[Anand Moon <linux.amoon@gmail.com>]

On Odroid c1 previously use gpio-hog to reset the usb hub,
switch to used on board usb hub reset to enable the usb hub
and enable power to usb hub.

Add usb hub regulator as per the schematic.

v2 - drop the vendor name from compatible string.
   - move the hub node to USB controller node.
   - drop the usb_otg_pwr since it only liked to OTG port
     and link p5v0 to the vdd-supply.
