[PATCH v6 2/5] dt-bindings: display: bridge: ldb: Adjust imx6sx entries

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

On the i.MX6SX there is a single entry for 'reg', so add some logic to
reflect that.

Dependency: This depends on bd60d98a11da ("dt-bindings: display: bridge: ldb: Adjust imx6sx entries"),
which is available on linux-next.

Changes since v5:
- Dropped reg-names for imx6sx (Marek).
- Indicated the dependency to avoid error when Rob's robot runs.
