[Intel-gfx] [PATCH v2] drm/i915/xehpsdv: add initial XeHP SDV definitions

[Matt Roper <matthew.d.roper@intel.com>]

From: Lucas De Marchi <lucas.demarchi@intel.com>

XeHP SDV is a Intel® dGPU without display. This is just the definition
of some basic platform macros, by large a copy of current state of
Tigerlake which does not reflect the end state of this platform.

v2:
 - Switch to intel_step infrastructure for stepping matches. (Jani)
