ALSA: hda - Update mixer name for the lower codec address
In most cases, we prefer the onboard codec as the primary device, thus
it's better to set it as the mixer name. Currently, however, the
mixer name is updated per the device instantiation order, and user
gets often HDMI/DP or other seen as a mixer chip name. Also, if a
codec name is renamed by the driver, the old chip name might be left
still as the mixer name.
This patch addresses these issues by remembering the chip address that
was referred as the mixer name. When a codec with the same or lower
address gives its name, renew the mixer name accordingly, as it's
either the update of the codec name or we get likely the more
appropriate chip as the reference.
