Remove support for fb events from the lcd subsystem. Provide the

lcd_notify_blank_all() to inform the lcd subsystem of changes

Fbdev maintains a list of all installed notifiers. Instead of fbdev
notifiers, maintain an internal list of lcd devices.
I don't love the LCD devices list, however I can see the list of notifiers
had the same semantic effect (only less explicit) so I can live with
it ;-).
v3:
- export lcd_notify_mode_change_all() (kernel test robot)
v2:
- maintain global list of lcd devices
- avoid IS_REACHABLE() in source file
- use lock guards
- initialize lcd list and list mutex

Happy with these changes, but have the same EXPORT_SYMBOL_GPL()
questions I did with the backlight code.
As in backlight.c, all existing symbols are exported with
EXPORT_SYMBOL(). I simply used what was already there.
Best regards
