GREYBUS_AUDIO_MSM8994 is not an existing configuration option and as reported in September 2016, it depends on an "out-of-tree qualcomm audio driver". This driver never made it upstream.

https://lore.kernel.org/lkml/20160921073905.GA31263@kroah.com/

Moreover, there doesn't seem to be any interest in actually fixing the driver as it uses ASoC APIs that have been removed from the kernel in 2018 as shown by its use of snd_soc_register_codec and snd_soc_codec_get_drvdata, removed in commit 999f7f5af8eb ("ASoC: remove Codec related code").
