Muralidhara M K 32ecdf8688 EDAC/amd64: Split read_mc_regs() into dct/umc functions
Call them from their respective hw_info_get() paths.

ECC symbol size is not needed on UMC systems, so determine_ecc_sym_sz()
is left out of the UMC path. Do not save TOP_MEM* values on modern
controllers because they're not needed there (read: they were used only
for debugging, if anything).

  [ Yazen: rebased/reworked patch and reworded commit message. ]
