Some new AMD cards have HDA codecs presenting 6 connected HDMI/DP pin nodes (plus 1 unconnected pin node) according to the ALSA card database.
Example: http://www.alsa-project.org/db/?f=de3ced7af41de0ed54d218650e5e2f16c511787b
Bump the maximum number of presented HDMI outputs per card via the "hdmi" PCM from 4 to 8 (so that the last possible device is DEV=7).
Note that HDMI PCM devices DEV=4..7 use shared PCM device numbers, so HDA cards that have over 4 audio PCM devices or multiple S/PDIF or modem devices will have their remaining PCM devices misrepresented as HDMI devices.

I do not have confirmed that all of these pins are actually usable (and therefore this patch is untested on affected hardware), but I guess that is probable. Maybe the large amount of them has something to do with DisplayPort supporting multiple displays via a single connector, but that is just a wild guess on my part...
But do we want some sort of a solution for the possible conflicts between non-HDMI devices in the 10+ physical PCM device numbering range?
