Luck, Tony f5a90d44a1 EDAC/Intel: Do not load EDAC driver when running as a guest 
[ Upstream commit f0a029fff4a50eb01648810a77ba1873e829fdd4 ]

There's little to no point in loading an EDAC driver running in a guest:
1) The CPU model reported by CPUID may not represent actual h/w
2) The hypervisor likely does not pass in access to memory controller devices
3) Hypervisors generally do not pass corrected error details to guests

Add a check in each of the Intel EDAC drivers for X86_FEATURE_HYPERVISOR
and simply return -ENODEV in the init routine.
