ARM: dts: am5729: beaglebone-ai: adding device tree 

BeagleBoard.org BeagleBone AI is an open source hardware single
board computer based on the Texas Instruments AM5729 SoC featuring
dual-core 1.5GHz Arm Cortex-A15 processor, dual-core C66 digital
signal processor (DSP), quad-core embedded vision engine (EVE),
Arm Cortex-M4 processors, dual programmable realtime unit
industrial control subsystems and more. The board features 1GB
DDR3L, USB3.0 Type-C, USB HS Type-A, microHDMI, 16GB eMMC flash,
1G Ethernet, 802.11ac 2/5GHz, Bluetooth, and BeagleBone expansion
headers.

For more information, refer to:
https://beaglebone.ai



This patch introduces the BeagleBone AI device tree.

Note that the device use the "ti,tpd12s016" component which is
software compatible with "ti,tpd12s015". Thus we only use the
latter driver.
