arm64: dts: ti: k3-j721e: Add support for pm2 som

The Beta EVMs will be having pm2 SoM which is mainly having Leo PMIC
instead of the prior pm1 SoM which has TPS65917 PMIC. Long term
support is for pm2 SoM.

So k3-j721e-som-p0.dtsi now points to the pm2 SoM &
k3-j721e-common-proc-board is pointing to the boards with pm2 SoM.

The older TPS65917 based pm1 SoMs are renamed to k3-j721e-som-tps65917.dtsi
& ti/k3-j721e-proc-board-tps65917.dts respectively.
