[RFC 08/13] ASoC: Intel: avs: Declare path and its components

[Cezary Rojewski]

Declare representatives for all crucial elements which stream on ADSP
side is made of. That covers pipelines and modules subject which are
presented by struct avs_path_pipeline and avs_path_module respetively.
While struct avs_path_binding and struct avs_path do not represent any
object on firmware side directly, they are needed to help track the
interconnections and membership of every pipeline and module created.
