block: Support providing LCHS from user
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.
