Mostly Matt Roper's kernel patch commit message:
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.
The remaining DG2 IDs for add-in cards will be enabled in a future
patch once some additional required functionality has fully landed.
