EDAC/amd64: Adjust address translation for Hygon family 18h model 4h 

Add Hygon family 18h model 4h processor support for DramOffset and
HiAddrOffset, and get the socket interleaving number from DramBase-
Address(D18F0x110).

Update intlv_num_chan and num_intlv_bits support for Hygon family 18h
model 4h processor.
