[PATCH v2 01/10] drm: Include <linux/backlight.h> where needed

[Thomas Zimmermann]

Include <linux/backlight.h> in source files that need it. Some of
DRM's source code gets the backlight header via drm_crtc_helper.h
and <linux/fb.h>, which can leed to unnecessary recompilation. If
possible, do not include drm_crtc_helper.h any longer.
