PM: QoS: Drop PM_QOS_CPU_DMA_LATENCY and rename related functions

Browse Source 
Drop the PM QoS classes enum including PM_QOS_CPU_DMA_LATENCY,
drop the wrappers around pm_qos_request(), pm_qos_request_active(),
and pm_qos_add/update/remove_request() introduced previously, rename
these functions, respectively, to cpu_latency_qos_limit(),
cpu_latency_qos_request_active(), and
cpu_latency_qos_add/update/remove_request(), and update their
kerneldoc comments.  [While at it, drop some useless comments from
these functions.]

No intentional functional impact.
