ALSA: Add the driver for Digigram Lola PCI-e boards
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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
