mce, edac: Use an atomic notifier for MCEs decoding
Add an atomic notifier which ensures proper locking when conveying
MCE info to EDAC for decoding. The actual notifier call overrides a
default, negative priority notifier.
Note: make sure we register the default decoder only once since
mcheck_init() runs on each CPU.
