Renamed to Digial SRC Capture Switch for more correct representation.
Also fixed analog volume control on Lola161611 and lola881.

For assuring the synchronized state with the pause operation,
loop over the all linked streams and waits until all get ready
in a loop.

Added granularity and sample_rate_min module options.
The former controls the h/w access granularity. As default, it's set
to the max value 32.
The latter controls the minimum sample rate in Hz, as default 16000.

Use a single BDL for both buffers instead of allocating for each.
Also a few tune-up to avoid the stream stalls in the PCM code and
the prelimianry work for SG-buffer support are added, too.

The codec proc file becomes a read only that shows the codec widgets
in a text form. A new proc file, codec_rw, is introduced instead for
accessing the Lola verb directly by reading and writing to it.
Also, regs proc file shows the contents of DSD, too.

Added a new driver for supporting Digigram Lola PCI-e boards.
Lola has a similar h/w design like HD-audio but with extended verbs.
Thus the driver is written similarly like HD-audio driver in the bus
part. The codec part is rather written in a fixed way specific to the
Lola board because of the verb incompatibility.
The driver provides basic PCM, supporting multi-streams and mixing.
