Subject: backlight: convert from legacy pm ops to dev_pm_ops
Convert drivers/video/backlight/class to use dev_pm_ops for power
management and remove Legacy PM ops hooks. With this change, backlight
class registers suspend/resume callbacks via class->pm (dev_pm_ops)
instead of Legacy class->suspend/resume. When __device_suspend() runs
call-backs, it will find class->pm ops for the backlight class.
