Subject: [PATCH V1 6/6] staging: greybus: audio: Enable GB codec, audio module compilation.

Currently, GB codec and audio module is conditionally compiled based on
GREYBUS_AUDIO_MSM8994. However, audio module is not dependent on MSM8994
platform and can be used generically with any platform that follows
GB Audio class specification.

Also, GB codec driver corresponds to dummy codec represented by I2S port
available on Toshiba AP Bridge. Added config option for the same in
kconfig file and accordingly updated Makefile.
