Dirk Brandewie 55e02d0a33 intel_pstate: Use LFM bus ratio as min ratio/P state ...

commit 4042e7570c upstream.

LFM (max efficiency ratio) is the max frequency at minimum voltage
supported by the processor.  Using LFM as the minimum P state
increases performmance without affecting power. By not using P states
below LFM we avoid using P states that are less power efficient.
