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.

This may just be a case of formality but we'd need "if
