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

[Abel Vesa]

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.

This stuff (and NAND) looks like it would belong to device nodes instead.

The rest seem fine though I'm not sure why exactly those clks are 
adjusted in vendor tree.
