USB: device DMA support on OMAP2
The current omap udc dosen't support the DMA mode and it has some problem
at setup time on OMAP2 with previous patch file. I found that the code
assumes bulk out required the big data transfer. But MODE SELECT(6) sent
the only 24 bytes. it makes a problem. So I implement the small packets
handling for it.
It is tested with both linux and windows.
