arm64: dts: imx8mm-evk: Enable audio codec wm8524
i.MX8MM has one wm8524 audio codec connected with
SAI3 digital audio interface.
This patch uses simple-card machine driver in order
to enable wm8524 codec.
We need to set:
* SAI3 pinctrl configuration
* codec reset gpio pinctrl configuration
* clock hierarchy
* codec node
* simple-card configuration
