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.
