PM / QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY
Support for adding per-device frequency limits was removed in
commit 2aac8bdf7a0f ("PM: QoS: Drop frequency QoS types from device PM QoS")
after cpufreq switched to use a new "freq_constraints" construct.
Restore support for per-device freq limits but base this upon
freq_constraints. This is primarily meant to be used by the devfreq
subsystem.
This removes the "static" marking on freq_qos_apply but does not export
it for modules.
