Was a bit confused in both of them actually. Updated the message v3.

Currently AM68 SK boots with J721s2 R5 DTS and then later changes to AM68 SK DT during runtime. To split the support of J721s2 and AM68, sync AM68 R5 DT with J721s2 R5 DT as that contains some essential node changes for booting up AM68 using AM68 R5 DT. secure_proxy_mcu and secure_proxy_sa3 node changes are required for establishing contact with TIFS running on M4 core, and the addition of new power domain helps in holding A72 in reset for configuration of firewalls.
