The Intel NVDIMM command specification publishes a dirty-shutdown-count
in addition to the dirty-shutdown / flush-failed indication that comes
from the ACPI NFIT. This is expected to be a common property of NVDIMMs
and is a static hardware health detail to be cached / exported via
sysfs.
Add plumbing for retrieving this data at driver load time, publish the
count, and use the dynamically retrieved dirty-shutdown indicator to
augment the existing 'flush_failed' flag.
