meta-ti-bsp: add BeagleBone AI-64 support

BeagleBone AI-64 (https://beagleboard.org/ai-64) uses Texas Instruments
Jacinto TDA4VM/J721e SoC. Officially BeagleBone AI-64 supports Debian
Linux and builds its BSP on top of meta-ti and TI SDK, but adds custom
DTBs and DTBO overlays, plus integrates other drivers and features.

Let's add corresponding recipes for beagleboard.org kernel and u-boot
along with the BeagleBone AI-64 machine config.
