From: "J. Neuschäfer" <[email protected]>
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@... in many existing devicetrees,
but this contradicts the simple-bus binding.

Looks consistant with mpc83xx platforms.

For correctness with dt-bindings documentation format check with DT
maintainers/reviewers.
Changes in v4:
- Rebase on v6.15-rc1
