[alsa-devel] [PATCH v2 3/7] ASoC: Intel: Skylake: Commonize parsing of format tokens

From: Shreyas NC <shreyas.nc at intel.com>

Format resource tokens can be a part of either the widget or manifest
private data. In the current model, format resources come as a part of
widget private data and they come as a part of topology manifest in the
newly introduced model.

So add a common function that can fill up either of the structures.
