Changes since v2: [1] - switch from non-idiomatic srcu synchronization of the device registration state to rwsem protection of the cxlmd->cxlm pointer. (Jason)

A collection of fixes initially inspired by Jason's recognition of dev_set_name() error handling mistakes on other driver review, but also from a deeper discussion of idiomatic device operation shutdown flows. The end result is easier to reason about and validate. Thank you, Jason.
The sysfs_emit() fixup and unpublishing of device power management files are independent sanity cleanups.
