edac: move dimm properties to struct dimm_info

Browse Source 
On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.

However, such assumption is not true for all types of memory
controllers.

Controllers for FB-DIMM's don't have such requirements.

Also, modern Intel controllers seem to be capable of handling such
differences.

So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.

The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.
