[PATCH v3 4/5] arm64: dts: imx8mq: Enable SAI2 for wm8524 codec

[Daniel Baluta]

This enables SAI2 digital audio interface to be used with
wm8524 codec.

wm8524 works only in slave mode, so we make sure that IMX8MQ_CLK_SAI2
has an appropriate frequency in order to easily derive rates divisible
with 8000.
