[PATCH] EDAC: e752x byte access fix

The reading of the DRA registers should be a byte at a time (one register at a
time) instead of 4 bytes at a time (four registers).  Reading a dword at a
time retrieves erroneous information from all but the first register.  A
change was made to read in each register in a loop prior to using the data in
those registers.
