[PATCH v4] dt-bindings: powerpc: Add Freescale/NXP MPC83xx SoCs

[J. Neuschäfer via B4 Relay]

From: "J. Neuschäfer" <j.ne at posteo.net>

Add a new binding for MPC83xx platforms, describing the board compatible
strings used in currently existing device trees.

Note that the SoC bus is called immr at ... in many existing devicetrees,
but this contradicts the simple-bus binding.

Changes in v4:
- Rebase on v6.15-rc1

V4:
- Try to list all existing compatible strings for MPC83xx boards

V3:
- split out as a single patch
- otherwise no changes

V2:
- part of series [PATCH v2 00/12] YAML conversion of several Freescale/PowerPC DT bindings
  Link: https://lore.kernel.org/lkml/20250207-ppcyaml-v2-1-8137b0c42526@posteo.net/
- trim subject line
- fix property order to comply with dts coding style
- add Rob Herrings's R-b tag
