fbdev: Send old blank state in FB_EVENT_BLANK
The event FB_EVENT_BLANK sends the new blank state in the event's
data field. Also send the old state. It's an additional field in the
data array; existing receivers won't notice the difference.
The backlight subsystem currently tracks blank state per display per
backlight. That is not optimal as it ties backlight code to fbdev. A
subsystem should not track internal state of another subsystem. With
both, new and old, blank state in FB_EVENT_BLANK, the backlight code
will not require its own state tracker any longer.
