We now have pr_err(), pr_warning(), and friends ... start using
them in the gadget stack instead of printk(KERN_ERR) and friends.
This gives us shorter lines and somewhat increased readability.

Keep track of the device status (as returned by the GET_STATUS
request) and allow it to be manipulated by set_selfpowered() as
well as SET_FEATURE/CLEAR_FEATURE (for remote wakeup)

Implement the wakeup() op, which refuses to do anything if the
DEVICE_REMOTE_WAKEUP feature wasn't set by the host.  Now this
driver passes USBCV (at least, with gadget zero).

Fix one more locking bug; lockdep is every developer's friend.

This is a driver for the Atmel USBA UDC which can be found integrated
on AT32AP700x AVR32 processors. For hardware documentation, please see
the AT32AP7000 data sheet:

http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf

This is a dual speed controller (connects at high or full speed).
The driver supports up to 7 control, bulk, interrupt and isochronous
endpoints with some constraints. Bulk, interrupt and isochronous
transfers are driven by DMA.
