[Intel-gfx] [PATCH] drm/i915: Add wrapper for getiing display step

[Animesh Manna]

From: Chaitanya Kumar Borah <chaitanya.kumar.borah at intel.com>

Add a wrapper around intel_step_name to maintain compatibility with xe
driver. The wrapper will share the same name as the one to be used by
xe while both drivers include different files as needed during
compilation.
