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.
