Subject: [PATCH 1/2] ARM: dts: am5729-beaglebone-ai: Enable IPU & DSP rprocs

Assign the previously added CMA reserved memory nodes to the respective
IPU and DSP rproc device nodes, and enable these rproc nodes so that
these remote processors can be booted on the AM5729 BeagleBone AI board.

The addresses and sizes of the CMA pools are identical to those used on
various other TI AM572x/AM574x based boards. The mailboxes, timers and
watchdog-timers for all these remoteprocs are inherited by including the
common dra72-ipu-dsp-common.dtsi file.

An associated pair of the rproc node and its CMA node can be disabled
later on if there is no use-case defined to use that remote processor.
