cpufreq: Remove references to 10ms min sampling rate

A minimum sampling rate value of 10ms was introduced in:
commit cef9615 ("[CPUFREQ] ondemand: Uncouple minimal sampling rate from HZ in NO_HZ case")

The use of this value was removed in:
commit ed4676e ("cpufreq: Replace "max_transition_latency" with "dynamic_switching"")

Remove:
- a comment referencing this value
- an unused macro associated to this value
