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.
