MMC: Move Samsung specific e-MMC code out of generic code

I originally put the command to read the SMART information out of
Samsung e-MMCs in the generic code because I thought I needed to
use private MMC interfaces to accomplish it.  I now know better
and am moving the command out to its own separate file.
