There was no users left - so drop the code to support EARLY_EVENT_BLANK.
This patch removes the support in backlight,
and drop the notifier in fbmem.
That EARLY_EVENT_BLANK is not used can be verified that no driver set any of:
lcd_ops.early_set_power()
lcd_ops.r_early_set_power()
Noticed while browsing backlight code for other reasons.
v2:
- Fix changelog to say "EARLY_EVENT_BLANK" (Daniel)
