fb_info->bl_mutex is badly thought out and the backlight class doesn't
need it if the framebuffer/backlight register/unregister order is
consistent, particularly after the backlight locking fixes.

Fix the drivers to use the order:

backlight_device_register()
register_framebuffer()
unregister_framebuffer()
backlight_device_unregister()

and turn bl_mutex into a lock for the bl_curve data only.

The backlight core listens for blanking events and triggers a
backlight_update_status call so these extra calls are not
needed and can be removed.

Remove uneeded update_status call from chipsfb.c since the
backlight core now receives software blanking notifications
too.
Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>

The backlight class wants notification whenever the console is blanked
but doesn't get this when hardware blanking fails and software blanking
is used. Changing FB_EVENT_BLANK to report both would be a behaviour
change which could confuse the console layer so add a new event for
software blanking and have the backlight class listen for both.

Currently its possible to build the backlight core as a module yet
compile the drivers into the kernel which gives missing symbols.

Fix.

nvidia_bl_set_power isn't needed since the backlight class handles
this by receiving fb events itself and calling update_status so

Convert internal semaphore to a mutex
Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>

backlight_device->sem has a very specific use as documented in the
header file. The external users of this are using it for a different
reason, to serialise access to the update_status() method.

backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.

Locking for get_brightness remains optional since most users don't
need it.

Also update the lcd class in a similar way.
