[COMMON] PM: Fixed debugging information for pm_qos in kernel 4.4.

[COMMON] PM: Fixed debugging information for pm_qos in kernel 4.4.

During debugging or profiling, pm_qos list like below is useful information.

	device_throughput
		default value: 0
		target value: 468000
		requests:
			ffffffc0012896f8: 0
			ffffffc06f2f0458: 0

But only pm_qos_request declared for global name space could find what it is.
If pm_qos_request declared in local name space, its address doesn't appeared in
System.map file.

So add more information about pm_qos_request's position like below.

	device_throughput
		default value: 0
		target value: 468000
		requests:
			ffffffc0012896f8(lpass_probe:1027): 0
			ffffffc06f2f0458(fimg2d_pm_qos_add_bus:170): 0
