Enable the otg/drc usb controller on the A10s OLinuxIno Micro.
Note the A10s OlinuxIno Micro always has some voltage on its otg power
pin, even if the usb-vbus0-regulator is disabled, the leaked voltage is
enough to make vbus-det always report 1, so we do not use vbus-det on
this board.

Changes in v2:
-Address usb0_vbus_pin_a node by reference instead of by full path
