dt-bindings: drm/bridge: ti-sn65dsi83: drop $ref to fix lvds-vod* warnings

The kernel test robot reported a warning related to the use of "$ref"
type definitions for custom endpoint properties
- "ti,lvds-vod-swing-clock-microvolt" and
- "ti,lvds-vod-swing-data-microvolt".

Using "$ref" with "uint32-array" is not correctly handled in this
context. Removing "$ref" and relying solely on "maxItems: 2" enforces
the intended requirement of specifying exactly two values, without
triggering a schema validation warning.
