Subject: [PATCH] Added mmcblk device type MMC

Added the abbreviation MMC for mmcblk devices such as SD and
microSD cards and some low budget laptops.

Changed log message from "USB bridge, no pass-through support"
to "Smart data unavailable" as no smart data could be caused by
a non USB device such as mmcblk as well as USB devices with no ATA
pass through and other devices that smartctl does not detect.
