Subject: [PATCH 24/28] sound: Call cpu_latency_qos_*() instead of pm_qos_*()

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

Call cpu_latency_qos_add/update/remove_request() and
cpu_latency_qos_request_active() instead of
pm_qos_add/update/remove_request() and pm_qos_request_active(),
respectively, because the latter are going to be dropped.

No intentional functional impact.
