[PATCH] USB: pxa2xx_udc updates
This has several small updates to the px2xx UDC driver:
* small fixes from Eugeny S. Mints <emints@ru.mvista.com>
- local_irq_save() around potential endpoint disable race
- fix handling of enqueue to OUT endpoints (potential oops)
* add shutdown() method to disable any D+ pullup
* rename methods accessing raw signals, referencing the signals
* describes itself as for "pxa25x", since pxa27x is different
