ASoC: Intel: Skylake: Add NHLT support to get BE config
The Non-HD Audio Endpoint Description table contains the link
configuration information for the DSP. This is specific to Non HDA
links only, like I2s and PDM
Skylake driver will use NHLT table to retrieve the configuration based
on the link type, format, channel and rate. This configuration is
passed to DSP FW
