Subject: [PATCH 5.7 176/179] ASoC: Intel: bdw-rt5677: fix non BE conversion

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

commit fffebe8a8339c7e56db4126653a3bc0c0c5592cf upstream.

When SOF is used, the normal links are converted into DPCM ones. This
generates an error

[ 58.276668] bdw-rt5677 bdw-rt5677: CPU DAI spi-RT5677AA:00 for rtd
Wake on Voice does not support playback
[ 58.276676] bdw-rt5677 bdw-rt5677: ASoC: can't create pcm Wake on
Voice :-22

Fix by forcing the capture direction.
