ARM: dts: DRA74x: Add IPC sub-mailbox nodes for all IPUs & DSPs
Add the sub-mailbox nodes that are used to communicate between
MPU and the remote processors IPU1, IPU2, DSP1 and DSP2.
The sub-mailbox nodes utilize the System Mailbox instances 5 and 6.
These sub-mailbox nodes are added to match the hard-coded mailbox
configuration used within the TI IPC 3.x software package. The
Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to
be running in SMP-mode, and hence only a single sub-mailbox node
is added for each.
All these sub-mailbox nodes are left in disabled state, and should
be enabled (and modified if needed) as per the individual product
configuration in the corresponding board dts files.
