From: Jacky Bai <ping.bai@xxxxxxx> Add the basic dts file for i.MX8ULP EVK board. Only the necessary devices for minimal system boot up are enabled: enet, emmc, usb, console uart. some of the devices' pin status may lost during low power mode, so additional sleep pinctrl properties are included by default.
