[Intel-gfx] [PATCH v2 01/50] drm/i915/xelpd: add XE_LPD display characteristics

Let's start preparing for upcoming platforms that will use an XE_LPD
design.

v2:
 - Use the now-preferred "XE_LPD" term to refer to this design
 - Utilize DISPLAY_VER() rather than a feature flag
 - Drop unused mbus_size field (Lucas)
