At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

For testing it is useful to be able to select the font size and the console
driver for sandbox. Add this information to platform data and copy it to
the video device when needed.

Add tests that check that the video console is working correcty. Also check
that text output produces the expected result. Test coverage includes
character output, wrapping and scrolling.

Now that driver model support is available, convert sandbox over to use it.
We can remove a few of the special hooks that sandbox currently has.

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.
