MLK-19118-4: ARM: dts: add supply for audio codec on audio board
There is a change in imx8mm evk revb board, which is to add a i2c
control for power enablement of audio board, that software can
control the power of audio board, which can resolve the issue that
with audio board the cpu board can't reboot issue.
In this patch add power supply for each AK series codecs
