audiopolicy: fix rsubmix / device with dynamic address regressions

Orphan devices (aka devices not declared in configuration file) used to be
managed by apm::mAvailable<Output|Input>Devices and affinity with profile
was done by type only.
As the device affinity with profile is now enforced by checking with descriptor
rather than with type, profile's supported devices list shall be dynamically
updated.

Test: manual audio smoke tests
