972560fb9d ide-cd: move VERBOSE_IDE_CD_ERRORS code to ide-cd_verbose.c
* Rename ide-cd kernel module to ide-cd_mod in preparation to moving code out
  from ide-cd.[c,h].   Add MODULE_ALIAS("ide-cd") to preserve compatibility.

* Move VERBOSE_IDE_CD_ERRORS code from ide-cd.[c,h] to ide-cd_verbose.c.

  ide-cd_verbose.c is IDE subsystem independent and may be easily converted
  into generic library usable by other drivers (i.e. libata) if needed.

* Add CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS config option to drivers/ide/Kconfig
  replacing VERBOSE_IDE_CD_ERRORS define.  Make this config option enabled by
  default and visible only if CONFIG_EMBEDDED is defined.

* Add IDE_CD_FLAG_VERTOS_{300_SDD,600_ESD} and IDE_CD_FLAG_SANYO_3CD flags.

* Move device quirks from ide_cdrom_setup() to ide_cd_quirks_list[].

* Rename IDE_CD_FLAG_NEC260 to IDE_CD_FLAG_PRE_ATAPI12 and handle
  quirky Stingray 8X CD-ROM using ide_cd_quirks_list[].

* Add IDE_CD_FLAG_FULL_CAPS_PAGE flag and handle quirky ACER 50X CD-ROM
  / WPI 32X CD-ROM using ide_cd_quirk_list[].

* Add IDE_CD_FLAG_PLAY_AUDIO_OK flag and handle quirky MATSHITA DVD-ROMs
  using ide_cd_quirks_list[].

* Add IDE_CD_FLAG_LE_SPEED_FIELDS flag and handle quirky ACER/AOpen 24X
  CD-ROM using ide_cd_quirk_list[].

* Fix some comments about quirky devices while at it.
