Subject: [PATCH] arm64: dts: imx8mn: Init rates and parents configs for clocks

From: Peng Fan <[email protected]>

Add the initial configuration for clocks that need default parent and rate
setting.

NoC sources from SYS PLL3, running at 600MHz. Audio AHB/IPG clks needs
to run at 400MHz for better performance.
