board: ti: j721s2: Add board_init and support for selecting DT based on EEPROM

Add the board_init_f API for SPL and run the platform-required SoC
initialization.

Add the functionality for board name-based DTB selection from FIT
within SPL. This will make it easier to utilise one defconfig for
both the EVM and the SK.
