Hi Takashi,

The Intel SandyBridge/CougarPoint HDMI codec is very similar to the
IbexPeak HDMI codec, except that it exports one more Audio Converter.

Now we have 3 Audio Converters, each of them present one HDMI PCM device:
(and expect a 4th HDMI PCM device in future)

	$ aplay -l | grep HDMI
	card 0: PCH [HDA Intel PCH], device 3: INTEL HDMI 0 [INTEL HDMI 0]
	card 0: PCH [HDA Intel PCH], device 7: INTEL HDMI 1 [INTEL HDMI 1]
	card 0: PCH [HDA Intel PCH], device 8: INTEL HDMI 2 [INTEL HDMI 2]

So enable devices minors to support more than 8 PCM playback devices.
