cxl/hdm: Default CXL_DEVTYPE_DEVMEM decoders to CXL_DECODER_DEVMEM
In preparation for device-memory region creation, arrange for decoders
of CXL_DEVTYPE_DEVMEM memdevs to default to CXL_DECODER_DEVMEM for their
target type.
Revisit this if a device ever shows up that wants to offer mixed HDM-H
(Host-Only Memory) and HDM-DB support, or an CXL_DEVTYPE_DEVMEM device
that supports HDM-H.
