[PATCH v3 3/5] board: ti: beagleboneai: add initial support

[Caleb Robey]

These are necessities for beaglebone ai boot. There is the addition of
CONFIG_SUPPORT_EMMC_CONFIG to the Kconfig file. This is present upstream
but not in 19.01 yet.

v2 Changes:
        - board.c changes that were present in previous commits
          were erroneously left out. Reintroduced for the
          sake of configuring the bbai once it is detected.
