The two DACs for the front output and the surround/center/LFE/back
outputs are wired up out of phase, so when channels are duplicated,
their sound can cancel out each other and result in a weaker bass
response. To fix this, reverse the polarity of the neutron flow to
the front output.

All Xonar cards support S/PDIF input, but the cards without optical or
coaxial plugs have only undocumented pin connectors. Support for the
ST/STX was already added in a previous patch; this adds support for the
D1/DX (JP2), DG (J5), DS (J5), and HDAV Slim (J12).
Many thanks to Zoltan Miklos for testing the DS and DX.

Replace the get_i2s_mclk callback with tables of MCLK values. This

There are more models without a CD input than with one, so handle this
explicitly with a device_config flag to avoid having to define a control
filter callback to filter it out.

Add the possibility to route a mix of the two channels of stereo data to
the center and LFE outputs. Due to a WM8766 restriction, all surround
and back channels also get the mixed L/R signal in this case.

The check for the volume update latch bit was accidentally in the wrong

The Line and Mic inputs cannot be used at the same time, so the driver
has to automatically disable one of them if both are set. However, it
forgot to notify userspace about this change, so the mixer state would
be inconsistent. To fix this, check if the other control gets muted,
and send a notification event in this case.

For the WM8776 chip, this driver uses a different sample format and
more features than the Windows driver. When rebooting from Linux into
Windows, the latter driver does not reset the chip but assumes all its
registers have their default settings, so we get garbled sound or, if
the output happened to be muted before rebooting, no sound.
To make that driver happy, hook our driver's cleanup function into the
shutdown notifier and ensure that the chip gets reset.

In the original code the condition was always true (hopefully) because
