The backlight code currently uses fbdev's FB_BLANK_ constants to
represent power states UNBLANK and POWERDOWN. Introduce dedicated
backlight constants to remove this dependency on fbdev.

Patch 1 introduces BL_CORE_UNBLANK and BL_CORE_POWERDOWN, which
replace similarly named constants from fbdev. There's also
BL_CORE_NORMAL, which is required by a few drivers that appear
to use incorrect or uncommon blanking semantics.

The rest of the patchset converts backlight drivers. The new
constants' values are identical to the old ones, so the driver
conversion can be done one-by-one.

There are many more backlight drivers in other subsystems. These
can later be converted when the new constants have been merged.
Once merged, several include statements for <linux/fb.h> can be
removed (specifically under drivers/platform/x86/).

This patchset is part of a larger effort to implement the backlight
code without depending on fbdev and ultimatively remove fbdev
dependencies from the kernel.
