cpufreq: Documentation: Update description of rate_limit_us default value

Browse Source 
Due to commit 37c6dccd68 ("cpufreq: Remove LATENCY_MULTIPLIER")
updating the acquisition logic of cpufreq_policy_transition_delay_us(),
the original description of 2 ms has become inaccurate.

Therefore, update the description of the default value for
rate_limit_us from 2ms to 1ms.

@ -439,7 +439,7 @@ This governor exposes only one tunable:
``rate_limit_us``
Minimum time (in microseconds) that has to pass between two consecutive
runs of governor computations (default: 1.5 times the scaling driver's
transition latency or the maximum 2ms).
transition latency or 1ms if the driver does not provide a latency value).
The purpose of this tunable is to reduce the scheduler context overhead
of the governor which might be excessive without it.
