[PATCH v5 3/3] arm64: dts: freescale: add i.MX95 19x19 EVK minimal board dts

From: Peng Fan <peng.fan at nxp.com>

Add a minimal dts for i.MX95 19x19 EVK board:
 - lpuart1 as console
 - sdhc1/2 as storage

As of now, because scmi pinctrl support not ready, so count on
bootloader to set the pinctrl.
