dmaengine: ti: k3-psil: optimize struct psil_endpoint_config for size

Optimize struct psil_endpoint_config for size by
- reordering fields
- grouping bitfields
- change mapped_channel_id type to s16 (32K channel is enough)
- default_flow_id type to s16 as it's assigned to -1

dmaengine: ti: k3-psil: Extend psil_endpoint_config for K3 PKTDMA

Additional fields needed for K3 PKTDMA to be able to handle the mapped
channels (channels are locked to handle specific threads) and flow ranges
for these mapped threads.
PKTDMA also introduces tflow for tx channels which can not be found in
K3 UDMA architecture.

dmaengine: ti: k3 PSI-L remote endpoint configuration

In K3 architecture the DMA operates within threads. One end of the thread
is UDMAP, the other is on the peripheral side.

The UDMAP channel configuration depends on the needs of the remote
endpoint and it can be differ from peripheral to peripheral.

This patch adds database for am654 and j721e and small API to fetch the
PSI-L endpoint configuration from the database which should only used by
the DMA driver(s).

Another API is added for native peripherals to give possibility to pass new
configuration for the threads they are using, which is needed to be able to
handle changes caused by different firmware loaded for the peripheral for
example.
