backlight: Convert from struct class_device to struct device
Convert the backlight and LCD classes from struct class_device
to struct device since class_device is scheduled for removal.
One nasty API break is the backlight power attribute has had to be
renamed to bl_power and the LCD power attribute has had to be renamed
to lcd_power since the original names clash with the core. I can't see
a way around this.
