[PATCH v2 03/12] drm/i915: Decouple intel_fb_bo.h interfaces from driver specific types

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Make the intel_fb_bo.h interfaces operated purely in base
drm_ types so that each driver (i915 and xe) doesn't have to
know about each other, or the display stuff.

v2: s/dev/drm/ (Jani)
