This patch converts the resource management in PCI lola driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

The BDL entries in lola driver are little-endian while we code them as
u32. This leads to sparse warnings like:
sound/pci/lola/lola.c:105:40: warning: incorrect type in assignment (different base types)
sound/pci/lola/lola.c:105:40: expected unsigned int [unsigned] [usertype] <noident>
sound/pci/lola/lola.c:105:40: got restricted __le32 [usertype] <noident>
This patch fixes the declarations to the proper __le32 type.
Also, there was a typo in the original code, where __user was used
that was intended as __iomem. This was caused also by sparse:
sound/pci/lola/lola_mixer.c:132:27: warning: incorrect type in assignment (different address spaces)
Fixed in this patch as well.

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

Added the refcounting for the exclusive SRC control.
Also, fixed the possible stall after PCM pause operations.

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.

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.
