dma: ti: k3-udma: Add support for native configuration of chan/flow
In absence of Device Manager (DM) services such as at R5 SPL stage, driver will have to natively setup TCHAN/RCHAN/RFLOW cfg registers. Existing UDMA driver performed the above mentioned configuration for UDMA. Add similar configuration for PKTDMA here.
