Current cxl core is relying on a CXL_DEVTYPE_CLASSMEM type device when
creating a memdev leading to problems when obtaining cxl_memdev_state
references from a CXL_DEVTYPE_DEVMEM type. This last device type is
managed by a specific vendor driver and does not need same sysfs files
since not userspace intervention is expected.

Create a new cxl_mem device type with no attributes for Type2.

Avoid debugfs files relying on existence of cxl_memdev_state.

"Avoid debugfs files that rely on existence of cxl_memdev_state."

Currently it means you keep the files but break their reliance
on that state. So subtly different from what is implemented.

It makes sense.

I'll fix it in v10.

Thanks!

Make devm_cxl_add_memdev accesible from a accel driver.
