video: mdss: Set initial backlight after first frame done

 * Garbage is randomly appearing during unsuspend on the Truly panel.
 * Userspace is updating the backlight sysfs very quickly (good), but in
   some cases there is random garbage in frame memory which might
   end up being displayed to the user (bad).
 * Update the backlight after the first frame done in this case
   to make sure any random crap left in the frame memory is overwritten
   by a proper image.

asoc: wcd9xxx: Detect more types of headsets

 * With the triple-checked recalibration, the invalid range check is
   causing more harm than good. We've been narrowing this range over
   time, and it's not solving any problems. Kill it with fire.
 * Also raise the delta range to accomodate more variations.
