mako: backlight: sync backlight on/off with lcd on/off

Browse Source 
To avoid dispalying garbage during lcd on/off, the turning on
lcd should be done before backlight on and turning off backlight
should be finished before lcd off. But current implementation
doesn't guarantee these on/off sequence. This patch ensure the
sequence of lcd and backligth on/off.
