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.
