Separate out RPLU device ids and add them to both RPL and
newly created RPL-U subplatforms.

v2: (Matt)
   - Sort PCI-IDs numerically
   - Name the sub-platform to accurately depict what it is for
   - Make RPL-U part of RPL subplatform

v3: revert to RPL-U subplatform (Jani)

v4: (Jani)
   - Add RPL-U ids to RPL-P platform

drive by comment while reviewing other stuff. Why was U added to the
P macro? That looks odd. Adding it to the rpl subplatform, together with P would
be ok, but in this macro it looks wrong. Doing it the other way I think the
only affected place would be the early-quirks, which would need a separate entry,
but admitedly they should had been INTEL_RPL_IDS() with all the
variants.
