sunxi: Hookup OTG USB controller support



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.

---help---
Say y here to enable support for the sunxi OTG / DRC USB controller
used on almost all sunxi boards. Note currently u-boot can only have
one usb host controller enabled at a time, so enabling this on boards
which also use the ehci host controller will result in build errors.
