ASoC: cygnus: Remove support for 8 bit audio and for mono
These modes of operation were not working properly and it is unclear if the hardware could fully support these modes properly. There is little to be gained by enabling these modes, therefore, we will just remove support. Signed-off-by: Lori Hikichi <lori.hikichi@broadcom.com> Signed-off-by: Mark Brown <broonie@kernel.org>
