dmaengine: at_xdmac: fix bug about channel configuration
When using descriptor view 2 or higher, we don't write the configuration into AT_XDMAC_CC register because this configuration will be fetch from the descriptor. Unfortunately, the PROT bit is not updated with this method, we have to do it manually before enabling the channel.
