USB: omap_udc: sync with OMAP tree
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.
