ASoC: pcm: allow delayed suspending request by users
If a device would like to use delayed suspending then PM recommendation is to set ‘power.use_autosuspend’ flag. To allow users to do so we need to change runtime calls in core to use autosuspend counterparts. For user who do not wish to use delayed suspend not setting the device's ‘power.use_autosuspend’ flag will result in non-delayed suspend even with these APIs which incidentally is also the default behaviour, so only users will be impacted who opt in for this.
