[PATCH v2 3/6] arch: arm: dts: k3-am68-sk-r5: Sync with J721s2 R5 file

[Manorit Chawdhry]

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.
