USB: omap_udc: workaround dma_free_coherent() bogosity
Various fixes to omap_udc, noted with some recent testing:
- Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent()
implementation: alloc() can be called with IRQs blocked, but since late
last year that's no longer true for free(). This resolves really NASTY
problems with logspamming via WARN_ON(), indicating N-page leaks.
- Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the
previous code only handled RECIP_INTERFACE, this version should be correct
except for (sigh) bulk/interrupt endpoints.
- Provide a better name for the function reporting whether the board has
vbus sensing wired up.
GET_STATUS requests for endpoint status still acts strangely though, at least
given one flakey host doesn't always ack the first DATA packet, then the packet
that gets retransmitted doesn't have data!
