ASoC: Intel: Skylake: Add multiple pin formats

The module pin formats are considered homogeneous, but some
modules can have different pcm formats on different pins, like
reference signal for a module.

This patch add support for configuration of each pin of module
and allows us to specify if pins and homogeneous or heterogeneous
