[Intel-gfx] [PATCH] drm/i915: fix non-DP-D eDP backlight cleanup and module reload

[Jani Nikula]

Backlight is initialized for eDP, but cleaned up only for eDP on DP-D
port. This leaves behind a dangling backlight interface on module unload on
machines that have eDP connected to something other than DP-D, and breaks
the backlight interface for subsequent module reloads. Fix the cleanup, and
thus module reload on affected machines.
