sunxi: ohci: Add ohci usb host controller support

This commit adds support for the OHCI companion controller, which makes
usb-1 devices directly plugged into to usb root port work.

Note for now this switches usb-keyboard support for sunxi back from int-queue
support to the old interrupt polling method. Adding int-queue support to the
ohci code and switching back to int-queue support is in the works.
