dm: Add a demonstration/example driver
As an example of how to write a uclass and a driver, provide a demo version
of each, accessible through the 'demo' command.
To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO.
The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and
CONFIG_DM_DEMO_SHAPE.
