board: ti: beagleboneai: emmc read changes
BeagleBoard.org BeagleBone AI rev A1 does not include a board
identifier I2C EEPROM due to a design oversight. These boards have
been put into production and are generally available now.
The board identifier information, however, has been included in the
second eMMC linear boot partition (/dev/mmcblk1boot1).
This patch works by:
* First, looking for a board identifier I2C EEPROM and if not found,
* Then seeing if the boot mode matches BeagleBone AI with eMMC in the
boot chain to make sure we don't enable eMMC pinmuxes on boards
that don't support it, and
* Finally, initializes the eMMC pins and reading the header.
