virtio_blk: add block topology support
Allow reading various alignment values from the config page. This
allows the guest to much better align I/O requests depending on the
storage topology.
Note that the formats for the config values appear a bit messed up,
but we follow the formats used by ATA and SCSI so they are expected in
the storage world.
