[ Upstream commit 914f8b228ede709274b8c80514b352248ec9da00 ]
This adds a function to update a CGR with new parameters. qman_create_cgr
can almost be used for this (with flags=0), but it's not suitable because
it also registers the callback function. The _safe variant was modeled off
of qman_cgr_delete_safe. However, we handle multiple arguments and a return
value.

The possibility of a timeout being used with a PM QoS request incurs
overhead for *all* PM QoS requests due to the necessary calls to
cancel_delayed_work_sync().
Furthermore, using a timeout for a PM QoS request can lead to disastrous
results on power consumption. It's always possible to find a fixed scope in
which a PM QoS request should be applied, so timeouts aren't ever strictly
needed; they're usually just a lazy way of using PM QoS.
Remove the timeout API to eliminate the added overhead for non-timeout PM
QoS requests, and so that timeouts cannot be misused.
