[PATCH 01/15] drm/i915/display: identify discrete graphics

[Jani Nikula <jani.nikula@xxxxxxxxx>]

Identify discrete graphics separately in display, using the platform
group mechanism. This enables dropping the dependency on i915_drv.h
IS_DGFX() from display code.

Start grouping platform groups separately in INTEL_DISPLAY_PLATFORMS()
in anticipation of more groups to come.
