Add a simple LCD driver which uses SDL to display the image. We update the
image regularly, while still providing for reasonable performance.

Adjust the common lcd code to support sandbox.

For command-line runs we do not want the LCD to be displayed, so add a
--show_lcd option to enable it.

to an aligned address + 2 to avoid unaligned access exception
on some ARM platforms.

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).

Conflicts:

Replaced the functionality of callbacks by using a standard set of functions.
Instead of implementing and hooking up a callback, put the same code in one of
the standard set of functions by overriding it.

This patch is tested only on SMDK5250.
For Trats and universal_c210 board, it is only compile tested.
