Support 192kHz remote submix paths for E-AC-3(-JOC) IEC 61937

Explicitly reject remote submix non PCM input or output streams, so that
AudioFlinger can retry opening compressed audio streams using IEC61937
encapsulation.

Remove the Format_from_SR_C() comment from sample_rate_supported as that
function no longer limits by sample rate. A complete cleanup of
audio_hw.cpp to remove stale references to Format_from_SR_C() is
deferred.
