Subject: [PATCH v3 1/6] dt-bindings: reset: fsl,imx8mp-audiomix-reset: add bindings

The Audio Block Control contains clock distribution and gating
controls, as well as reset handling to several of the AUDIOMIX
peripherals. Especially the reset controls for Enhanced Audio
Return Channel (EARC) PHY and Controller.

Add DT-Schema bindings for the reset function in i.MX8MP audiomix
block controller.
