On Exynos5420 and newer versions, the FIMD sysmmus are in
"on state" by default.
We have to disable them in order to make FIMD DMA work.
This patch adds the required framework to exynos_fimd driver,
and disables FIMD sysmmu on Exynos5420.

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.

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).

Add LCD definitions and also a proposed binding for LCD displays.
The PWM is as per what will likely be committed to linux-next soon.
The displaymode binding comes from a proposal here:
http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html
The panel binding is new, and fills a need to specify the panel
timings and other tegra-specific information. Should a binding appear
that allows the pwm to handle this automatically, we can revisit
this.
