From: Alejandro Lucero <alucerop@amd.com>

Avoiding to send the full type2 support patchset until there is an
agreement about how to do the cxl initialization from accel drivers.

Using the idea from fwctl for embedding cxl_dev_state in a private
accel driver struct and a macro helping for the allocation and
initialization of such struct.

The main problem is the amount of internal cxl structs which need to be
public for accel drivers which we tried to avoid since v1 of the type2
patchset history.

Alejandro Lucero (2):
  cxl: add type2 device basic support
  sfc: add cxl support
