USB: omap_udc: sync with OMAP tree

Browse Source 
Sync up USB parts of the omap_udc support in mainline with the OMAP tree.
This patch addresses some OMAP2 differences ... there's another, with
respect to the double-buffering issue with PIO-IN in omap_ep_setup()
(which is now out of sync with the comments), but it's not clear right
now how to address that.
