PM / QOS: Pass request type to dev_pm_qos_{add|remove}_notifier()
In order to use the same set of routines to register notifiers for different request types, update the existing dev_pm_qos_{add|remove}_notifier() routines with an additional parameter: request-type. For now, it only supports resume-latency request type but will be extended to frequency limit (min/max) constraints later on.
