PM / QoS: Prepare device structure for adding more constraint types
Currently struct dev_pm_info contains only one PM QoS constraints pointer reserved for latency requirements. Since one more device constraints type (i.e. flags) will be necessary, introduce a new structure, struct dev_pm_qos, that eventually will contain all of the available device PM QoS constraints and replace the "constraints" pointer in struct dev_pm_info with a pointer to the new structure called "qos".
