[PATCH 01/63] ide-cd: fix SAMSUNG CD-ROM SCR-3231 quirk

[Bartlomiej Zolnierkiewicz]

cdi->mask is cleared by ide_cdrom_register() which is called after the quirk.

Fix it by adding new ->no_speed_select flag to struct ide_cd_config_flags
and using it in ide_cdrom_register() to set CDC_SELECT_SPEED flag.
