backlight: convert drivers/video/backlight/* to use module_platform_driver()
...
Convert the drivers in drivers/video/backlight/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

backlight: add backlight type
...
There may be multiple ways of controlling the backlight on a given
machine. Allow drivers to expose the type of interface they are
providing, making it possible for userspace to make appropriate policy
decisions.

backlight: Allow properties to be passed at registration
...
Values such as max_brightness should be set before backlights are
registered, but the current API doesn't allow that. Add a parameter to
backlight_device_register and update drivers to ensure that they
set this correctly.

backlight: Rename the corgi backlight driver to generic
...
The corgi backlight driver is really generic code. This rename makes
this a lot clearer and completes the partial rename made a while ago.
