amd64_edac: build driver only on AMD hardware

-tip testing found the following build failure (config attached):

drivers/built-in.o: In function `amd64_check':
amd64_edac.c:(.text+0x3e9491): undefined reference to `amd_decode_nb_mce'

the AMD EDAC code has a dependency on CONFIG_CPU_SUP_AMD facilities. The
patch below solves the problem here.
