arm64: dts: imx8mq-evk: Enable audio codec wm8524
The main Audio DAC used on the EVK board is wm8524
The EVK provides the MCLK to wm8524.
Digital interface is SAI2 which includes three signals:
SYNC_CLK, BCLK and DACDAT.
This patch sets:
* SAI2 pinctrl configuration
* clock hierarchy
* wm8524 codec
Then uses simple-card machine driver to connect them
into a sound card.
