ata: libata-scsi: add support for the REMOVE ELEMENT AND MODIFY ZONES command
Define the translation for the REMOVE ELEMENT AND MODIFY ZONES command (SERVICE ACTION IN command with service action SAI_REMOVE_ELEMENT_AND_MODIFY_ZONES) into the ATA command ATA_CMD_REMOVE_ELEMENT_AND_MODIFY_ZONES with the new function ata_scsi_remove_element_and_modify_zones_xlat() The array of supported commands ata_supported_cmds is modified to add a new entry for this command. ata_scsi_cmd_is_supported() is also modify to correctly handle this new entry depending on the target device flag ATA_DFLAG_DEPOP being set, and the target device being a ZAC zoned device.
