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.
