[1/2] arm64: dts: ti: k3-am62p: Enable Mailbox nodes at the board level

Commit Message

Andrew Davis Dec. 3, 2024, 5:41 p.m. UTC

Mailbox nodes defined in the top-level J722s/AM62p SoC dtsi files are
incomplete and may not be functional unless they are extended with a
chosen interrupt and connection to a remote processor.

Disable the Mailbox nodes in the dtsi files and only enable the ones
that are actually used on a given board.
