Since SMPS10 and OTG cable detection extcon are described here, and work to enable OTG power when an OTG cable is plugged in, we can define OTG mode in the controller (which is disabled by default in omap5.dtsi).
Tested on OMAP5EVM and Pyra.

Works fine on my uevm, except that it's usb2.0 only.
On my pyra it doesn't seem to send power to the port, my usb power meter doesn't turn on at least. The usb3 hub does get created, but it doesn't detect anything plugged in (which isn't that surprising without power).
