amd64_edac: check only ECC bit in amd64_determine_edac_cap
Checking whether the machine is using ECC enabled DRAM is done through testing the DimmEccEn bit in the DRAM Cfg Low register (F2x[1,0]90). Do that instead of testing all bits from the DimmEccEn upwards. Also, remove mci->edac_cap assignment and use value returned from amd64_determine_edac_cap().
