ide-cd: rename cdrom_* functions to ide_cd_*
* cdrom_prepare_request() -> ide_cd_init_rq() * cdrom_queue_packet_command() -> ide_cd_queue_pc() * cdrom_lockdoor() -> ide_cd_lockdoor() * cdrom_read_toc() -> ide_cd_read_toc() * cdrom_get_toc_entry() -> ide_cd_get_toc_entry() This is a preparation to move code handling cdrom.c IOCTLs out of ide-cd.c.
