[PATCH v5 3/4] ARM: dts: imx6ull-colibri: Set LCDIF bus width

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini at toradex.com>

The Colibri family standard defines an 18-bit parallel RGB interface on
the edge connector. The additional six LCDIF data signals required for a
24-bit interface are mapped to module-specific pins whose location is not
fixed across the Colibri family and which may not be available at all.

Generic Colibri carrier boards can therefore only rely on an 18-bit
interface. Set the LCDIF bus-width property accordingly.

A 24-bit interface can still be used by a specific carrier and module
combination by overriding the property in the carrier board device tree.
