Add emulation of the Messaging Unit and wire it into the
i.MX8MP SoC model. The MU provides inter-processor
communication between the Cortex-A53 and Cortex-M7 cores on the
i.MX8MP SoC. It is used by the Linux remoteproc framework as a
mailbox for lifecycle management and message passing with the
Cortex-M7 in an AMP configuration.
