ide: split off ioctl handling from IDE settings (v2)
* do write permission and min/max checks in ide_procset_t functions
* ide-disk.c: drive->id is always available so cleanup "multcount" setting
accordingly
* ide-disk.c: "address" setting was incorrectly defined as type TYPE_INTA,
fix it by using type TYPE_BYTE and updating ide_drive_t->adressing field,
the bug didn't trigger because this IDE setting uses custom ->set function
* ide.c: add set_ksettings() for handling HDIO_SET_KEEPSETTINGS ioctl
* ide.c: add set_unmaskirq() for handling HDIO_SET_UNMASKINTR ioctl
* handle ioctls directly in generic_ide_ioclt() and idedisk_ioctl()
instead of using IDE settings to deal with them
* remove no longer needed ide_find_setting_by_ioctl() and {read,write}_ioctl
fields from ide_settings_t, also remove now unused TYPE_INTA handling
v2:
* add missing EXPORT_SYMBOL_GPL(ide_setting_sem) needed now for ide-disk
