bb5930d5c9 exynos: video: Convert several boards to driver model for video
Update several boards to use driver model for video. This involves changes
to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration
since they use the device tree settings in the same way as Linux.

Boards converted are:
- snow
- spring
- peach-pit
- peach-pi

All have been tested. Not converted:

- MIPI display driver
- s5pc210_universal
- smdk5420
- smdk5250
- trats
- trats2

e23c6c28b0 video: Allow simple-panel to be used without regulators
At present simple-panel requires regulator support and will not build
without it. But some panels do not have a power supply, or at least not one
that can be controlled. Update the implementation to cope with this.

d76592122b tegra: nyan-big: Move the LCD driver to driver model
Adjust the driver to use driver model. The SOR becomes a bridge device. We
use the normal simple_panel driver to handle the display itself. We also
need to enable some options such as regulators, PWMs and DM_VIDEO itself.

cd9c2070ea video: panel: Add a simple panel driver
Most panels are very simple - they just have a power supply and a backlight.
Add a driver which supports this and implements the enable_backlight()
method.
