ALSA: hda - Increment default stream numbers for AMD HDMI controllers
It turned out that some AMD HDMI controllers still don't provide proper values in GCAP register (all zero), and the driver assigns only one stream in that case, although the connected codec chip supports more than one stream. In this patch, the default max number of streams for AMD HDMI controllers is increased to 8, which should suffice for most use cases. The overhead by this increase is more azx_dev struct and BDL allocations, so it's negligible. Of course, if the controller provides a proper GCAP register, the register value would be used.
