[PATCH v1 3/3] arm64: dts: imx8mp-var-smarc: Add support for Variscite Echo board

[Stefano Radaelli <stefano.radaelli21@gmail.com>]

From: Stefano Radaelli <stefano.r@variscite.com>

Add device tree support for the Variscite Echo carrier board with the
VAR-SMARC-MX8M-PLUS system on module.

The Echo board includes:
- uSD card support
- USB ports and OTG
- Two Gigabit Ethernet interfaces
- UART, SPI and I2C interfaces
- HDMI display interface
- WM8904 audio codec
- Capacitive touchscreen
- GPIO expanders, buttons and LED
- PCIe interface
- CAN peripherals
