Claude review: dt-bindings: leds: Document TI LM3533 LED controller

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

The bindings are mostly well-structured, but have some issues:

**Overly restrictive required list**: The top-level binding requires ALL child nodes:
```yaml
required:
  - compatible
  - reg
  - light-sensor
  - backlight@0
  - backlight@1
  - led@2
  - led@3
  - led@4
  - led@5
```
Not every board will use all six control banks plus ALS. Most real boards will only use a subset. This should use `patternProperties` matching without making every child `required`, or at minimum reduce the required set to just `compatible` and `reg`.

**`led-sources` maximum off-by-one in leds binding**: The `ti,lm3533-leds.yaml` defines `items: maximum: 5`, but the LVLED indices are 0-4, so the maximum should be `4`:
```yaml
  led-sources:
    items:
      maximum: 5    # should be 4
```

**Minor**: The `ti,resistor-ohm` property description says "resister" instead of "resistor."
