[Intel-gfx] [PATCH v2 15/50] drm/i915/xehpsdv: add initial XeHP SDV definitions

Wed Jul 14 03:15:05 UTC 2021
From: Lucas De Marchi <lucas.demarchi at 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)
Bspec: 44467, 48077
