configs: am62x_evm: Add dtbo support
- Add support of device tree overlay for Android to support CSI camera,
LVDS screen, HDMI Audio output.
- Support for multiple dtbo indices.
This assumes that the `dtbo_index` env variable is a space-separated
list of indices.
Example:
=> env set dtbo_index "0 2"
