x86 EDAC, sb_edac.c: Take account of channel hashing when needed
Haswell and Broadwell can be configured to hash the channel
interleave function using bits [27:12] of the physical address.
On those processor models we must check to see if hashing is
enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and
act accordingly.
