ASoC: intel: sof_sdw: Move sdw_pin_index into private struct
Whilst it should not cause any issues as only a single instance of the
machine will be instantiated, it is still slightly better practice to
keep working data in the private data structure, rather than a global
variable. Move sdw_pin_index into the mc_private structure.
