[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
