libata: add command name parsing for error output
This patch improve libata's output for error/notification messages to allow easier comprehension and debugging: When ATAPI commands issued through the SCSI layer fail, use SCSI functions to print the CDB in human-readable form instead of just dumping out the CDB in hex. Print out the name of the failed command (as defined by the ATA specification) in error handling output along with the raw register contents. When reporting status of ACPI taskfile commands executed on resume, also output the names of the commands being executed (or not) in readable form. Since the extra data for printing command names increases kernel size slightly, a config option has been added to allow disabling command name output (as well as some of the error register parsing) for those highly sensitive to kernel text size.
