ASoC: Intel: avs: New gateway configuration mechanism

Creation of a module which contains gateway configuration consists of
few additional steps, namely:

- assigning ID (node_id) for the gateway
- attaching hardware configuration from the NHLT table (optional)

By splitting the steps into separate functions code becomes easier to
read and understand. Any redundancy created by this patch will be
addressed by follow up changes.
