Add working USB HID driver, by Tomer Shalev (part of his GSoC work).

This needs support for usb interrupt transfers, so there are some changes in various USB drivers as well (only usb-drv-arc supports it at this point, others won't have working HID yet).

HID is disabled for now, as the apps/ part is not included yet.
