MLK-23350-7 arm64: dts: imx8mp-evk-sof: Enable simple-audio-card for SAI3 + wm8960
We use existing simple-audio-card machine driver to demonstrate
the usage of SAI3 + wm8960 codec.
FSL DAI driver is used in order to manage SAI resources (PD, clocks,
pinctrl) the rest is taken care of by the SAI driver from the DSP.
