[PATCH 2/2] ARM: dts: am5729-beaglebone-ai: Disable ununsed mailboxes

[Suman Anna]

The IPU and DSP remote processors use sub-mailbox nodes only from a
limited set of System Mailboxes 5 and 6 to achieve the Remote Processor
Messaging (RPMsg) communication stack between the MPU host processor
and the respective remote processor. These are all defined and enabled
through the inherited common dra74-ipu-dsp-common.dtsi file.

The other System Mailboxes do not define any actual sub-mailboxes, so
they serve no purpose and can all be safely dropped.
