dmaengine: ti: k3-udma: Add PSIL threads for AM62P and J722S

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:
