[PATCH 4/9] arm64: dts: imx8ulp: Add assigned clock properties for LPUART nodes

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

Add assigned-clocks, assigned-clock-parents and assigned-clock-rates
properties to lpuart4 through lpuart7, so the LPUART input clock is
configured automatically by the clock framework during probe.
