modules/sensors: Try intel scaling current frequency

Browse source 
On intel pstate drivers only the normal frequency is written to /proc/cpuinfo, not accounting for scaling/turbo.
This should fix that, though it needs testing on other computers (AMD, intel without pstate) because I am not
certain that the file only exists on Intel pstate.
