Introduce scsitool for sony nwz players

This tool can send vendor specific scsi commands to sony nwz
players such as getting serial number, model id, device info,
and others. It can potentially be used to get some private keys
stored on the device but probably not the KAS used to encrypt
firmware upgrades images(UPG).
