Virtio-blk extended lifetime feature
...ded to include more cell types, since its current implementation
in virtio spec is relevant for MMC and UFS devices only.
The VIRTIO_BLK_F_LIFETIME defines the following fields:
- pre_eol_info: the percentage of reserved blocks that are consumed.
- device_lifetime_est_typ_a: wear of SLC cells.
- device_lifetime_est_typ_b: wear of MLC cells.

Following Michael's suggestion, I'd like to add to the virtio spec
with a new, extended lifetime command.
Since I'm more familiar with embedded type storage devices, I'd like
to ask you guys what...
