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_MACHINE".
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.
