Subject: [PATCH RFC 0/2] cxl: Further clean up of memdev state

Dan has identified issues with the way the CXL core manages data within
the cxl_memdev_state object.[1]  Rather than just change DCD, clean up
cxl_memdev_state prior to DCD so the addition of DCD is consistent.

These clean ups are based on top of Dan's re-architect of the handling
of DPA partitions. [2]  They are intended to land after his v3 of that
set which is due out.
