[Intel-xe] [RFC 1/3] drm/i915: Add wrapper for xe compatibility

[Chaitanya Kumar Borah <chaitanya.kumar.borah@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.
