ASoC: tegra-alt: Fix audio capture/playback across suspend

Browse Source

If audio capture/playback is active when the device enters system
suspend then the sound core does not correctly suspend capture/playback
and so when the system is resumed, audio capture/playback does not
continue. The problem is that the various DAI links have the property
'ignore_suspend' set and this causes the sound core to skip suspending
any active PCM streams and hence, the DMA controller is not
stopped/paused as it should be on entering suspend or started/resumed
as it should be on exiting suspend. Fix this by removing the
'ignore_suspend' properties for the various DAI links.
