[PATCH v3 12/13] backlight: as3711_bl: introduce backlight_is_blank()

[Sam Ravnborg <sam@ravnborg.org>]

Replaces the open-coded checks of the state, with the
backlight_is_blank() helper. This increases readability
of the code and aling the functionality across the drivers.

Futhermore drop the debug prints in update_status().
If we need debug printing then we can add it to the backlight core.
