Two carveout reserved memory nodes each have been added for each of the
C71x DSP for the TI K3 AM69 SK boards. These nodes are assigned to the
respective rproc device nodes as well. The first region will be used as
the DMA pool for the rproc device, and the second region will furnish
the static carveout regions for the firmware memory.

The current carveout addresses and sizes are defined statically for each
device. The C71x DSP processor supports a MMU called CMMU, but is not
currently supported and as such requires the exact memory used by the
firmware to be set-aside.
