[PATCH] USB: omap_udc updates

This is a collection of updates to the OMAP UDC driver.

  - OMAP-1510 support, including DMA (the DMA controller isn't quite
    the same as on newer chips) but not double buffering.

  - Some PIO work:

      * fix some races that showed up on OMAP-1510

      * tracking down annoying PIO-OUT lossage and making double buffering
        start to behave (needed as fallback if all DMA channels are in use).

  - DMA-IN works on both 1510 and 16xx

Plus minor cleanups.
