From: Matt Roper <matthew.d.roper@xxxxxxxxx>
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)
v3:
- Adjust for dbuf.{size,slice_mask} (Ville)
