ALSA: oxygen: remove __dev* attributes

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

ALSA: virtuoso: add S/PDIF input support for all Xonars

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.

ALSA: Xonar, CS43xx: Don't overrun static array

'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of
8. So, this code in sound/pci/oxygen/xonar_cs43xx.c::dump_d1_registers()

for (i = 2; i <= 8; ++i)
snd_iprintf(buffer, " %02x", data->cs4398_regs[i]);

will overrun the array when 'i == 8'.

I guess that what's needed to fix it is the trivial patch below, but I
must admit that I have no idea about this code, so I may very well be
wrong. Additionally, I have no way to actually test this, so all I know is
that the below compiles. Someone who actually knows this code should take
a look before anything is comitted - consider the below (not much more
than) a bug report.

ALSA: virtuoso: fix front panel routing for D1/DX/ST(X)

The "Front Panel" switch on the Xonar D1/DX actually switches only the
output direction, so mark it appropriately.

The front panel microphone is controlled by the FMIC2MIC bit of the
CM9780. It was unconditionally enabled on the D1/DX and never set on
the ST(X); add a control for it. Selecting the front panel microphone
as source does not actually disable the microphone jack, but this is
bug-compatible with the Windows driver, and users rely on it.
