ALSA: hda: 92hd71xxx disable unmute support for codecs that don't have input amps

Some revisions of the 92hd71xxx codec families don't have input amps
on ports 0xa, 0xd and 0xf, so probe the widget caps on port 0xa and
check for support, if found run snd_hda_sequence_write_cache() on the
stac92hd71xxx_unmute_core_init verb list.
