A few SpeedStep-capable systems don't perform according to specification: the
CPUID and/or some MSRs don't tell us the CPU is SpeedStep capable even though
it definitely is. Allow a relaxed checking for one such issue by a module
parameter only available if a config option is turned on. This is done to
avoid the risk of doing invalid speedstep instructions on systems which do
not support it, and which might even lead to (hardware) failure.
