cxl/mbox: Flag support for Dynamic Capacity Devices (DCD)
Per the CXL 4.0 specification software must check the Command Effects
Log (CEL) for dynamic capacity command support.
Detect support for the DCD commands while reading the CEL, including:
Get DC Config
Get DC Extent List
Add DC Response
Release DC
Leave mds->dcd_supported false. Dynamic capacity is only usable once
the driver can handle Add and Release Capacity events. Detect and log
the capability here and let the commit which adds DCD event handling set
the flag.
Based on an original patch by Navneet Singh.
