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.

Please ignore this, I sent it from the wrong repo. I swear that I
double checked.
Will sent v2 with correct base.
