ALSA: hda - Disable runtime PM for Panther Point again

commit de5d0ad506cb10ab143e2ffb9def7607e3671f83 upstream.

This is essentially a partial revert of the commit [b1920c21102a:
'ALSA: hda - Enable runtime PM on Panther Point'].  There was a bug
report showing the HD-audio bus hang during runtime PM on HP Spectre
XT.
