intel_pstate: Fix BYT frequency reporting

Browse source

commit b27580b05e upstream.

BYT has a different conversion from P state to frequency than the core
processors.  This causes the min/max and current frequency to be
misreported on some BYT SKUs. Tested on BYT N2820, Ivybridge and
Haswell processors.
