ide-cd: remove struct ide_cd_{config,state}_flags
* Remove unused ->{writing,reserved} fields from struct ide_cd_config_flags. * Move ->max_speed from struct ide_cd_config_flags to struct cdrom_info. * Move ->current_speed from struct ide_cd_state_flags to struct cdrom_info. * Add defines for config and state flags. * Add 'unsigned int cd_flags' to struct cdrom_info and use ->cd_flags instead of ->{config,state}_flags. * Remove no longer needed struct ide_cd_{config,state}_flags.
