libata: Add support for SCT Write Same
SATA drives may support write same via SCT. This is useful
for setting the drive contents to a specific pattern (0's).
Translate a SCSI WRITE SAME 16 command to be either a DSM TRIM
command or an SCT Write Same command.
Based on the UNMAP flag:
- When set translate to DSM TRIM
- When not set translate to SCT Write Same
