Subject: [RFC PATCH] arm64: dts: fsl: wandboard: Add a device tree for the PICO-PI-IMX8M

From: Richard Hu <richard.hu@...hnexion.com>

The current level of support yields a working console and is able to boot
userspace from an initial ramdisk copied via u-boot in RAM.

Additional subsystems that are active :
	- Ethernet
	- USB
