In preparation for the per-device constratins support:
- rename update_target to pm_qos_update_target
- generalize and export pm_qos_update_target for usage by the upcoming
per-device latency constraints framework:
* operate on struct pm_qos_constraints for constraints management,
* introduce an 'action' parameter for constraints add/update/remove,
* the return value indicates if the aggregated constraint value has
changed,
- update the internal code to operate on struct pm_qos_constraints
- add a NULL pointer check in the API functions

In preparation for the per-device constratins support, re-organize
the data strctures:
- add a struct pm_qos_constraints which contains the constraints
related data
- update struct pm_qos_object contents to the PM QoS internal object
data. Add a pointer to struct pm_qos_constraints
- update the internal code to use the new data structs.

- Misc fixes to improve code readability:
* rename struct pm_qos_request_list to struct pm_qos_request,
* rename pm_qos_req parameter to req in internal code,
consistenly use req in the API parameters,
* update the in-kernel API callers to the new parameters names,
* rename of fields names (requests, list, node, constraints)

The PM QoS implementation files are better named
kernel/power/qos.c and include/linux/pm_qos.h.
The PM QoS support is compiled under the CONFIG_PM option.
