lcd: add functions to set up simplefb device tree
simple-framebuffer is a new device tree binding that describes a pre- configured frame-buffer memory region and its format. The Linux kernel contains a driver that supports this binding. Implement functions to create a DT node (or fill in an existing node) with parameters that describe the framebuffer format that U-Boot is using. This will be immediately used by the Raspberry Pi board in U-Boot, and likely will be used by the Samsung ARM ChromeBook support soon too. It could well be used by many other boards (e.g. Tegra boards with built-in LCD panels, which aren't yet supported by the Linux kernel).
