Dave Jiang 4474ce565e cxl/hdm: Create emulated cxl_hdm for devices that do not have HDM decoders
CXL rev3 spec 8.1.3

RCDs may not have HDM register blocks. Create a fake HDM with information
from the CXL PCIe DVSEC registers. The decoder count will be set to the
HDM count retrieved from the DVSEC cap register.
