[PATCH 6/7] cpufreq: make cpufreq_generic_init transition_latency default to CPUFREQ_ETERNAL

If no valid transition_latency specified, let's make it default to
CPUFREQ_ETERNAL which is consistent with its definition.

This can save some of the same checkings like this:
        transition_latency = dev_pm_opp_get_max_transition_latency(cpu_dev);
-       if (!transition_latency)
-               transition_latency = CPUFREQ_ETERNAL;
        ret = cpufreq_generic_init(policy, freq_table, transition_latency);
