[PATCH 02/12] ASoC: SOF: control: Add access field in struct snd_sof_control

[Daniel Baluta]

From: Ranjani Sridharan <ranjani.sridharan at linux.intel.com>

Add a new field to save the access setting for all controls
in struct snd_sof_control. This will be used to ensure that
only widgets belonging to static pipelines have volatile
controls.
