Yea that does sound better but I think this builds on your text and is even
more clear.

cxl/region: Add dynamic capacity decoder and region modes

One or more decoders each pointing to a Dynamic Capacity (DC) partition form a
CXL software region.  The region mode reflects composition of that entire
software region.  Decoder mode reflects a specific DC partition.  DC partitions
are also known as DC regions per CXL specification r3.1 but they are not the
same entity as CXL software regions.

Define the new modes and helper functions required to make the association
between these new modes.
