ALSA: Add the driver for Digigram Lola PCI-e boards

Browse Source 
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.
