Device configuration for building TWRP on Amlogic reference boards

Build notes:

• To get started with OMNI sources to build TWRP, check out the minimal manifest repo here.
• To save space, a shallow clone is recommended.
• These device configurations should be built with the twrp-9.0 branch.
• Copy this project to /device/amlogic/ directory.

More tips:

• To add busybox repository, add it to omni-default.xml
