Peter Ujfalusi e9ca48d9bf dmaengine: ti: k3-psil: add map for j7200
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)
