Add support for the TempoTec/MediaTek HiFier Serenade sound card.

The PCI ID was already there, but the driver handled it like the
Fantasia model, which resulted in a dummy recording device.  As
a stereo output-only card, this model is to be handled exactly
like the HG2PCI.

The snd-hifier driver contains more duplicated code than model-specific
code, so it does not make sense for it to be a separate driver.
Handling the two-channel output restriction can be easily done in the
generic driver.

The HT-Omega Claro halo's ADC is an AK5385 instead of a WM8785, so we
should handle the ADC parameters as we do with the X-Meridian.

Using the code for the wrong ADC does not seem to have any audible
effects, and the Windows driver does it, but it is nonetheless a good
idea to run the AK5385 with an oversampling ratio that is not outside
the documented limits.

Under as yet unknown circumstances, the first word of the sound card's
EEPROM gets overwritten.  When this has happened, we cannot rely on the
subsystem IDs that the kernel reads from the PCI configuration
registers.  Instead, we read the IDs directly from the EEPROM and do the
ID matching manually.

Because the model-specific driver cannot determine the model before
calling oxygen_pci_probe(), that function now gets a get_model()
callback as parameter.  The customizing of the model structure, which
was formerly done by the probe() callback, also has moved into
get_model().

Move the owner field out of the oxygen_model structure and make it
a parameter of oxygen_pci_probe(), because the actual owner module does
not depend on the card model.  Furthermore, moving it out of the model
structure allows us to create the card structure before the actual model
is known.

When changing the sample rate, the CMI8788's master clock output becomes
unstable for a short time.  The AK4396 needs the master clock to do SPI
writes, so writing to an AK4396 control register directly after a sample
rate change will garble the value.  In our case, this leads to the DACs
being misconfigured to I2S sample format, which results in a wrong
output level and horrible distortions on samples louder than -6 dB.

To fix this, we need to wait until the new master clock signal has
become stable before doing SPI writes.
