Revert "backlight/fbcon: Add FB_EVENT_CONBLANK"
This reverts commit 994efacdf9a087b52f71e620b58dfa526b0cf928.
The justification is that if hw blanking fails (i.e. fbops->fb_blank)
fails, then we still want to shut down the backlight. Which is exactly
_not_ what fb_blank() does and so rather inconsistent if we end up
with different behaviour between fbcon and direct fbdev usage. Given
that the entire notifier maze is getting in the way anyway I figured
it's simplest to revert this not well justified commit.
v2: Add static inline to the dummy version.
