[0/3] cxl: Misc fixups that missed v6.2

Message

While working on volatile region enumeration in the v6.1 timeframe I put
together these small fixups and a new attribute to help topology
walking. I overlooked them for v6.2, but will now target them for v6.3.

The most significant change is a 'parent_dport' attribute so 'cxl list'
has a simple method to identify the downstream port that routes to the
descendant cxl_port (upstream port).
