Some device ports are connected via ADSP which takes care
of the actual audio configuration (format, channels, SR),
for example the built-in speaker and mic ports, as well
as some external devices like analog headsets.
In the legacy implementation, such device ports did not have
any profiles specified. Allow the same behavior in the AIDL
implementation. To ensure correctness, device ports with no
profiles must be routable to mix ports that have profiles
specified. This requirement is fulfilled in legacy configs.
