audiopolicy: Modify logging in setOutputDevices

Modify logging in setOutputDevices to log ioHandles, mixport
names for better debugging.

Also, modify the method signature to include caller, as
setOutputDevices can be modified from multiple places,
having a caller context is helpful during multiple
device connection scenarios.

Test: Build and check logs while running usecases
