bootdevice: Gather LCHS from all relevant devices 

Relevant devices are:
    * ide-hd (and ide-cd, ide-drive)
    * scsi-hd (and scsi-cd, scsi-disk, scsi-block)
    * virtio-blk-pci

We do not call del_boot_device_lchs() for ide-* since we don't need to -
IDE block devices do not support unplugging.
