Btw, those DSC_SDTYPE_* defines are used only here to map to the MEM_*
ones. You can just as well use the naked numbers here and drop the
DSC_SDTYPE* ones as it is clear what the naked numbers mean based on how
they're being used.

DDR3 is silently added too, you can talk about that in the commit
message, for example.
