ASoC: Intel: avs: remove redundant dapm routes

Merge series from Brent Lu <brent.lu@intel.com>:

This patch series remove redundant dapm routes declared in multiple machine
drivers. These routes will be created by snd_soc_dapm_connect_dai_link_widgets()
during soundcard initialization. Following is the kernel log from a KBL
chromebook nocturne.
