Robert Nelson 45b0b5e5a0 arm: dts: Add k3-am625-beagleplay 
BeagleBoard.org BeaglePlay is an easy to use, affordable open source
hardware single board computer based on the Texas Instruments AM625
SoC that allows you to create connected devices that work even at long
distances using IEEE 802.15.4g LR-WPAN and IEEE 802.3cg 10Base-T1L.
Expansion is provided over open standards based mikroBUS, Grove and
QWIIC headers among other interfaces.

This board family can be identified by the 24c32 eeprom:

[aa 55 33 ee 01 37 00 10  2e 00 42 45 41 47 4c 45  |.U3..7....BEAGLE|]
[50 4c 41 59 2d 41 30 2d  00 00 30 32 30 30 37 38  |PLAY-A0-..020078|]

https://beagleplay.org/
https://git.beagleboard.org/beagleplay/beagleplay

baseline of base device tree is v6.5-rc1.
