[Intel-gfx] [PATCH] Don't ignore backlight level change to the same level.

[Matthias Hopf]

If set externally to a different level, this would result in a no-op.
OTOH if the display is switched off (DPMS) you do not want the change to take
place immediately, but rather to be saved and set later when the display is
active again.
