Based on ATA-ACS-4, recognize several bit fields related to the ATA
SANITIZE feature-set, Self-Encrypting Drives, and form-factor
identification.
The 'usedmovsd' field is not used in-tree. ATA-1 (1994) defined the word
for backwards-compatibility with a Vendor-Unique use, but it was marked as
Reserved starting with ATA-2 (1996). It stayed that way until ATA-8 (2008)
defined it as implemented in this change.
