[PATCH v4 6/7] staging: greybus: audio: Enable GB codec, audio module compilation.

[Vaibhav Agarwal]

Currently you can't enable the Gey Bus Audio Codec because there is no
entry for it in the Kconfig file. Originally the config name was going
to be AUDIO_MSM8994 but that's not correct because other types of
hardware are supported now. I have chosen the name AUDIO_APB_CODEC
instead.  Also I had to update the dependencies for GREYBUS_AUDIO to
make the compile work.
