Beagle Play has a different boot flow than the AM62x SK EVM.

AM62x SK EVM:
1. Boot rom reads UDA (User Data Area), looking for tiboot3
2. Boot rom finds tiboot3 and loads it

Beagle Play:
1. Boot rom looks for tiboot3 in mmc0boot0
2. Boot rom finds tiboot3 and loads it

Because of this difference, we need to have a different
partitioning table than the generic TI one.

Include generic TI android support and override the partitioning table
to boot Android.
