PM: QoS: Drop frequency QoS types from device PM QoS
There are no more active users of DEV_PM_QOS_MIN_FREQUENCY and DEV_PM_QOS_MAX_FREQUENCY device PM QoS request types, so drop them along with the code supporting them. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
