[Why] Timings with small HBlank (such as CVT RBv2) can result in insufficient HBlank bandwidth for audio SDP transmission when DSC is active. This will cause some higher bandwidth audio modes to fail. The combination of CVT RBv2 timings + DSC can commonly be encountered in MST scenarios. [How] Add DP audio bandwidth validation for 8b/10b MST and 128b/132b SST/MST cases and filter out modes that cannot be supported with the current timing config.
