audio: Match the r_submix configuration to the legacy impl
The legacy configuration was interesting because although the
xml config file only listed 48000 Hz SR and
AUDIO_CHANNEL_OUT_STEREO channel mask, the implementation
allowed a range of SRs and MONO channel mask. The framework was
liberally allowing requests for other SRs to go to the r_submix
HAL, even without having them listed in the xml config
file. However, since libaudiohal@aidl is more strict in matching
configuration requests to port capabilities, we need to list all
channels masks and SRs suported by the legacy HAL explicitly.
However, we need to limit the amount of profiles to avoid
extra load when passing them via AudioPolicyService.listAudioPorts,
thus remove other PCM types.
Also, to match the hard limit on the number of routes in the legacy
implementation, set "maxOpen/ActiveStreamCount" for mix ports.
