board: ti: am33xx: Add support for BeagleBoard Green Eco

SeeedStudio BeagleBone Green Eco (BBGE) is a clone of the BeagleBone Green
(BBG). It has minor differences from the BBG, such as a different PMIC,
a different Ethernet PHY, and a larger eMMC.

The PMIC is not yet supported in mainline, but the work is ongoing.
