ARM: ux500: Strip out duplicate USB DMA configuration
For the moment at least, the TX and RX channels for DB8500 USB are identical, so this patch generalises them into a single structure and passes it twice. Once as the TX and again for the RX configuration. We're keeping the infrastructure the same i.e. passing the TX and RX separately in case they start to differ on latter incarnations of the platform.
