From: Sam Eiderman <shmuel.eiderman@xxxxxxxxxx>
Add logical geometry variables to BlockConf.
A user can now supply "lcyls", "lheads" & "lsecs" for any HD device
that supports CHS ("cyls", "heads", "secs").
These devices include:
* ide-hd
* scsi-hd
* virtio-blk-pci
In future commits we will use the provided LCHS and pass it to the BIOS
through fw_cfg to be supplied using INT13 routines.
