MLK-19936-2 arch: arm64: fsl-imx8mm: add audio plls in micfil node 

Parse the clock tree and stop when you find one of the
audio_plls. If this audio_pll cannot support the required
rate, change the parent to the other pll.
Set rate to rate * 1024 so we can support all parameter
configurations with a minimum clock rate.
This is required to support all rates multiple of 11025 and 8000.
