Added audio-related stuff used on a few multimedia boards

From: Mauro Carvalho Chehab <mchehab@infradead.org>

Those files are not part of V4L stuff. However, they are or dependent of V4L 
apis or used on some video boards.
After this patch, it will be possible to compile and test they against changes
at V4L API or drivers.

+	---help---
+	  Audio DMA support for bt878 based grabber boards.  As you might have
+	  already noticed, bt878 is listed with two functions in /proc/pci.
+	  Function 0 does the video stuff (bt848 compatible), function 1 does
+	  the same for audio data.  This is a driver for the audio part of
+	  the chip.  If you say 'Y' here you get a oss-compatible dsp device
+	  where you can record from.  If you want just watch TV you probably
+	  don't need this driver as most TV cards handle sound with a short
+	  cable from the TV card to your sound card's line-in.
+
+	  To compile this driver as a module, choose M here: the module will
+	  be called btaudio.

+
+	  This VoxWare ACI driver currently supports the ACI functions on the
+	  miroSOUND PCM1-pro, PCM12 and PCM20 radio. On the PCM20 radio, ACI
+	  also controls the radio tuner. This is supported in the video4linux
+	  miropcm20 driver (say M or Y here and go back to "Multimedia
+	  devices" -> "Radio Adapters").
+
+	  This driver is also available as a module and will be called aci.
