[PATCH v3] dt-bindings: leds: Allow differently named multicolor leds

[PATCH v3] dt-bindings: leds: Allow differently named multicolor leds

[J. Neuschäfer via B4 Relay]

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

In some cases, for example when using multiple instances of
leds-group-multicolor, a board may have multiple multi-leds which can't
be distinguished by unit address. In such cases it should be possible to
name them differently, for example multi-led-0 and multi-led-1. This
patch adds another node name pattern to leds-class-multicolor.yaml to
allow such names.

V3:
- Combine patterns into one, instead of using oneOf schema
- Change examples in commit message to use numeric suffixes
- Restrict pattern to allow only numeric suffixes after the dash
  following Rob Herring's suggestion

V2:
- Link: https://lore.kernel.org/r/20250412-multi-led-v2-1-56af86908744@posteo.net
- Add Krzysztof's review tag
- mention leds-group-multicolor in the commit message
- rebase on 6.15-rc1
