[PATCHv2 6/7] board: ti: j721e: initialize ESM support

[Tero Kristo]

Initialize both ESM and ESM_PMIC support if available for the board.
If support is not available for either, a warning is printed out.

ESM signals are only properly routed on PM2 version of the J721E SOM,
so only probe the drivers on this device.
