[Intel-gfx] [PATCH v2 2/3] drm/i915: Add first set of DG2 PCI IDs

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

The IDs added here are the subset reserved for 'motherboard down'
designs of DG2.  We have all the necessary support upstream to enable
these now (although they'll continue to require force_probe until the
usual requirements are met).

The remaining DG2 IDs for add-in cards will come in a future patch once
some additional required functionality has fully landed.
