configs: am62x_android_a53.config: Store environment in MMC 

The android boot flow allows users to pick custom device tree overlays
to be applied for additional peripheral support.

This is done via an environment variable named "dtbo_index".
For example:

  => env set dtbo_index 2
  => saveenv

Allow users to save the environment so that the dtbos are applied on
each reboot.
