nitrogen6x: display: add support lvds jeida screen
Add support for Boundary Devices 7" and 10.1" 1280x800 displays with integrated FocalTech ft5x06 10-point touch controller. Because they share the touch controller with the 1024x600 displays, auto-detection is disabled and you must explicitly set the 'panel' environment variable: U-Boot > setenv panel LDB-WXGA U-Boot > saveenv && reset Signed-off-by: Robert Winkler <robert.winkler@boundarydevices.com> Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
