Hookup OTG USB controller support and enable the otg controller + USB-keyb on various tablets.

This allows tablet owners to interact with u-boot without needing to solder a serial console onto their tablet PCB.

Thanks. Works great on my Primo73 and Primo81 tablets. However I have just one naive question before happily taking it into use by default.

Is the hardcoded otg host mode (without checking the id pin) always safe? For example, what happens if somebody connects a charger instead of a usb keyboard to the tablet?
