Boot devices which use overriden LCHS values are:
* ata * ahci * scsi * esp * lsi * megasas * mpt * pvscsi * virtio * virtio-blk
We use these values in get_translation() and setup_translation() by introducing a new translation type: "TRANSLATION_HOST".
We treat this translation as TRANSLATION_NONE in fill_ata_edd(), although this does not really matter since now the translation between physical and logical geometry does not exist.
