intel/skylake: add nhlt support
The use of a NHLT table is required to make audio work on the skylake SoCs employing the internal DSP. The table describes the audo endpoints (render vs capture) along with their supported formats. These formats are not only dependent on the audio peripheral but also hardware interfaces. As such each format has an associated blob of DSP settings to make the peripheral work. Lastly, each of these settings are provided by Intel and need to be generated for each device's hardware connection plus mode/format it supports. This patch does not include the dsp setting blobs. The current supported connections: - digital mic array 2 channel - digital mic array 4 channel - Maxim 98357 amplifier - ADI ssm4567 - NAU88L25 headset codec BUG=chrome-os-partner:44481 BRANCH=None TEST=Built glados. Speakers, headphones, and mic on camera decently worked.
