liwei d93df29bda cpufreq: CPPC: fix perf_to_khz/khz_to_perf conversion exception 
When the nominal_freq recorded by the kernel is equal to the lowest_freq,
and the frequency adjustment operation is triggered externally, there is
a logic error in cppc_perf_to_khz()/cppc_khz_to_perf(), resulting in perf
and khz conversion errors.

Fix this by adding a branch processing logic when nominal_freq is equal
to lowest_freq.

Fixes: ec1c7ad476 ("cpufreq: CPPC: Fix performance/frequency conversion")
