During the migration to HDA core code, we lost the workaround for 4k BDL boundary. The flag exists in the new hdac_bus, but it's never set. This resulted in the sudden sound stall on some controllers that require this workaround like Creative Recon3D. This patch fixes the issue by setting the flag for such controllers properly.
