Subject: [PATCH v4 0/9] Add R5F and C7x DSP node for K3 J721S2, AM68 and AM69 SoCs

This series adds the R5F processor nodes and C7x DSP nodes for 
J721S2, AM68 and AM69 SoCs to align these nodes with other K3 SOC's node.

The first three patches adds the remote proc nodes to the SoC device
tree, remaining patches reserves the memory for remote proc IPCs
on K3 J721S2 EVM, AM68 SK, AM69 boards.

Note, K3 AM69 SoC derives from K3 J784S4 SoC, but is included in this
series as it was originally missed in the K3 J784S4 EVM rproc series.

https://lore.kernel.org/linux-arm-kernel/20230811202252.3586926-1-a-nandan@ti.com/

v3: Changelog:
1) Disabled c7x in k3-j721s2-main.dtsi and enabled in k3-j721s2-som-p0.dtsi
   which fixes the following dtbs_check for k3-am69-sk.dts
   - dsp@...00000: 'mboxes' is a required property
   - dsp@...00000: 'memory-region' is a required property
2) Split into separate patches for C7x and R5F

Link to v2:
https://lore.kernel.org/lkml/20230808201842.292911-1-a-nandan@ti.com/

v2:Changelog:
1) Added status = "disabled"; in soc dtsi files, and removed it from som dts
2) Fixed mboxes property in for all cores in som dts
