[PATCH v2 01/29] dt-bindings: soc: Add Realtek RTD1195 chip info binding

[Andreas Färber]

Define a binding for RTD1195 and later DHC SoCs' chip info registers.
Add the new directory to MAINTAINERS.

Signed-off-by: Andreas Färber <afaerber at suse.de>
---
 Note: The binding gets extended compatibly twice with additional properties.
 Could be squashed later if approved.
 
 v1 -> v2:
 * Dropped quotes for compatible (Rob)
 * Added additionalProperties: false (Rob)
