From: Sinthu Raja <sinthu.raja@ti.com>

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.

Changes in V3:
=============
Address review comments:
- Rework on DTB selection API clarity about mini-U-Boot vs EVM and family support as suggested.

v2: https://patchwork.ozlabs.org/project/uboot/cover/20221221135219.24702-9-sinthu.raja@ti.com/

This may just be a case of formality but we'd need "if 
defined(CONFIG_TI_I2C_BOARD_DETECT)" here as well right?
