Testing revealed the following error message for a CXL memdev that has
Feature support:
[ 56.690430] cxl mem0: Resources present before probing
Attach the allocation of cxl_fwctl to the parent device of cxl_memdev.
devm_add_* calls for cxl_memdev should not happen before the memdev
probe function or outside the scope of the memdev driver.
cxl_test missed this bug because cxl_test always arranges for the
cxl_mem driver to be loaded before cxl_mock_mem runs. So the driver core
always finds the devres list idle in that case.
