[U-Boot-Users] lcd patch

The attached patch fixes a bug in the common lcd code relating to font colours on 16bit displays (they were being and'd with 0xf, instead of 0xffff), and also adds a new config option CONFIG_LCD_NO_CONSOLE which disable initializing the device_t output device on the LCD (for when you only want to display a logo during boot).

The NO_CONSOLE option is probably not particularly useful, but I'm pretty sure the other bug is wrong.
