Hi,

Enable the otg/drc usb controller on the Wexler TAB7200 tablet.

Thanks, since this depends on the axp20x-usb-power-supply bits which are still pending I'll add this to my sunxi-wip tree, and then send it to Maxime together with a bunch of other otg enablement patches with the same dependency once those bits are merged.

The two newlines here should be only one, no need to resend I'll fix this when I merge it.
