[PATCH v4 0/3] Add NXP AUDMIX device and machine drivers

The patchset adds NXP Audio Mixer (AUDMIX) device and machine
drivers and related DT bindings documentation.

Changes since V3:
1. Removed machine driver DT bindings documentation.
2. Trigger machine driver probe from device driver as suggested by Nicolin.

Changes since V2:
1. Moved "dais" node from machine driver DTS node to device driver DTS node
  as suggested by Rob.

Changes since V1:
1. Original patch split into distinct patches for the device driver and
  DT binding documentation.
2. Replaced AMIX with AUDMIX in both code and file names as it looks more
  RM-compliant.
3. Removed polarity control from CPU DAI driver as suggested by Nicolin.
4. Added machine driver and related DT binding documentation.
