ASoC: Use finer grained dependencies in SND_SOC_ALL_CODECS

Move the bus dependencies in SND_SOC_ALL_CODECS into the individual
codec options rather than have them centrally. This allows the
inclusion of AC97 codecs when testing on platforms with AC97 support
and will also handle codecs on multi-function devices more gracefully.

           Normally ASoC codec drivers are only built if a machine driver which
           uses them is also built since they are only usable with a machine
           driver.  Selecting this option will allow these drivers to be built
           without an explicit machine driver for test and development purposes.
 
+	  Support for the bus types used to access the codecs to be built must
+	  be selected separately.

           If unsure select "N".
