x86/MCE: allow overriding the CMCI threshold

We've had reports of systems where CMCIs would surface at a relatively
high rate during certain periods of time, without them apparently
causing subsequent more severe problems (see Xeon E7-8800/4800/2800
specification clarification SC1). Give the admin a knob to lower the
impact on the system logs.
