Subject: [PATCH 12/12] ASoC: Intel: avs-ssm4567: remove redundant dapm routes

Four routes "Left Playback<-sspX Tx", "Right Playback<-sspX Tx",
"sspX Rx<-Left Capture Sense", and "sspX Rx<-Right Capture Sense" are
created by snd_soc_dapm_connect_dai_link_widgets() automatically.
Remove the duplicate routes.
