Subject: [PATCH 13/33] arm64: dts: ti: k3-am62p-j722s: Enable remote processors at board level
Remote Processors defined in top-level AM62P-J722S common SoC dtsi
files are incomplete without the memory carveouts and mailbox
assignments which are only known at board integration level.
Therefore, disable the remote processors at SoC level and enable them at
board level where above information is available.
