drm/i915: add some framework for backlight bl_power support
Make backlight class sysfs bl_power a sub-state of backlight enabled, if
a backlight power connector callback is defined. It's up to the
connector callback to handle the sub-state, typically in a way that
respects panel power sequencing.
v2: Post the version that does not oops. *facepalm*.
