[PATCH 07/16] blspec: support boot /dev/virtioblkX

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The device backing /dev/virtioblkX is called virtioY. The way the
bootloader spec code was written this results in the following working:

 - boot -l /dev/virtioblk0.1
 - boot -l virtio0
 - boot -l /mnt/virtioblk0.1

But not:

 - boot -l /dev/virtioblk0

Fix this by implementing the new .scan_disk callback. As scan_device is
just the fallback, remove the blspec_scan_disk call from it.
