Subject: [PATCH v4] arm64: dts: imx8mq: Init rates and parents configs for clocks

From: Abel Vesa <abel.vesa@....com>

Add the initial configuration for clocks that need default parent and rate
setting. This is based on the vendor tree clock provider parents and rates
configuration except this is doing the setup in dts rather then using clock
consumer API in a clock provider driver.

Note that by adding the initial rate setting for audio_pll1/audio_pll
setting we need to remove it from imx8mq-librem5-devkit.dts
