PM / OPP: Introduce dev_pm_opp_get_max_transition_latency()
In few use cases (like: cpufreq), it is desired to get the maximum latency for changing OPPs. Add support for that. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
