[PATCH v2 01/10] drm/i915/xe3lpd: reuse xe2lpd definition

[Matt Atwood <matthew.s.atwood@intel.com>]

From: Clint Taylor <clinton.a.taylor@intel.com>

xe3_lpd display is functionally identical to xe2_lpd for now so reuse
the device description.  A separate xe3 definition will be added in the
future if/when new feature flags are required.
