- Updated backlight_is_blank() based on Daniel's feedback
- Dropped EXPORT_SYMBOL that was no longer relevant

- Updated the description
The driver required initialization using struct generic_bl_info.
As there are no more references to this struct there is no users left.
So it is safe to delete the driver.

Drivers have not seen any love for years.
Be that fixes or improvements, or cosmetics like introducing symbolic
names, style and code-flow polish.
Seemingly the maintainer has also disappeared years ago :-\
Considering nouveau supports all that hardware (modulo nv03) just mark
these as obsolete/
