ALSA: hda/hdmi: Use only dynamic PCM device allocation

Browse source 
Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM
device mapping is obsolete nowadays. The maximum number of the simultaneously
usable PCM devices is equal to the HDMI codec converters.

Remove the extra PCM devices (beyond the detected converters) and force
the use of the dynamic PCM device allocation. The legacy code is removed.

I believe that all HDMI codecs have the jack sensing feature. Move the check
to the codec probe function and print a warning, if a codec without this
feature is detected.
