The codec-parsing of STAC925x was utterly broken due to its unique
design unlike other STAC codecs. It has a volume control only in NID
0x0e (similar as STAC9200), but the parser assumes that the amp is
available on each DAC widget.
The patch fixes the whole wrong stories: fix the initial volume,
assign the fixed "Master" volume, and avoid to create wrong volume
controls.

On the Asus Xonar D2 and D2X models, the SPI chip select signal for the
fourth DAC shares its pin with the serial clock for the EEPROM that
contains the PCI subdevice ID values. It appears that when DAC
registers are written and some other unknown conditions occur (probably
noise on the EEPROM's chip select line), the EEPROM gets overwritten
with garbage, which makes it impossible to properly detect the card
later.
Therefore, we better avoid DAC register writes and make sure that the
driver works with the DAC's registers' default values. Consequently,
the sample format is now I2S instead of left-justified (no user-visible
change), and the DAC's volume/mute registers cannot be used anymore
(volume changes are now done by the software volume plugin).

it's unneeded indeed for Dell laptops that have multiple headphones.
Setting the extra hp_nid results in a non-working "Headpohne" mixer

Also, the automatic addition of hp_nid should check whether it's
a dual-HP model or not. For dual-HPs, the pins are already checked
