Plumb support for the device advanced information CCB in the ATA XPT.

Browse Source 
This was previously done only for SCSI XPT in r223081, on which the change
in r223089 depended in order to respond to serial number requests.  As a
result of r223089, da(4) and ada(4) devices register a d_getattr for geom to
use to obtain the information.
