This adds a new binding for Sitronix ST7586 display panels.
Using lego as the vendor prefix in the compatible string because the display panel I am working with is an integral part of the LEGO MINDSTORMS EV3.

v4 changes: * Dropped optional properties and only use pins actually used on LEGO EV3. * Rename dc to a0 since that is what is on the datasheet/LEGO schematic.
