dmaengine: ti: k3-udma-glue: Add support for K3 PKTDMA
This commit adds support for PKTDMA in k3-udma glue driver. Use new
psil_endpoint_config struct to get static data for a given channel or a
flow during setup. Make sure that the RX flows being mapped to a RX
channel is within the range of flows that is been allocated to that RX
channel.
