Add PSIL thread information and enable UDMA support for AM62P
and J722S SoC. J722S SoC family is a superset of AM62P, thus
common PSIL thread ID map is reused for both devices.
For those interested, more details about the SoC can be found
in the Technical Reference Manual here:
AM62P - https://www.ti.com/lit/pdf/spruj83
J722S - https://www.ti.com/lit/zip/sprujb3

Add new PSI-L map file for the new TI j7200 SoC.
The DMA hardware in j7200 is the same as in j721e with different
set of peripherals resulting different PSI-L thread map compered
to j721e.
See J7200 Technical Reference Manual (SPRUIU1, June 2020)

[vkoul: updated patch title]
Signed-off-by: Vinod Koul <vkoul@kernel.org>
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.
