[PATCH v2 3/3] arm64: dts: imx8dxl: Add SolidRun SoM and HummingBoard

[Josua Mayer <josua@solid-run.com>]

Add support for the SolidRun i.MX8DXL System-on-Module (revision 2.1)
and its corresponding evaluation carrier board, the HummingBoard
Telematics (revision 2.0).

The SoM features:
- eMMC
- GNSS with 1PPS
- V2X DSRC Radio
- Secure Element for V2X Applications
- Inertial Sensor
- Pressure Sensor
- Compass

The HummingBoard Telematics carrier board features:
- Cellular Modem
- WiFi & Bluetooth
- RTC with backup battery
- CAN
- 100Base-TX Ethernet
- 100Base-T1 Ethernet
- Multi-interface I/O connector
- Multi-interface add-on board connector

The multi-interface I/O connector supplies power and provides basic I/O
(Console UART, 100Base-TX, 100Base-T1, CAN, and power-supply logic level
GPIOs). The SolidRun Evaluation Kit includes a suitable cable and
adapter board that breaks these out into RJ45, USB Type-A, microUSB
Console, and Terminal Block connectors.

The multi-interface add-on board connector provides additional
interfaces (4x 100Base-T1, 2x SGMII, USB 2.0 shared with the cellular
modem, CAN, MDIO, SPI, UART, PCIe, I2C, and GPIO). These add-on
interfaces are disabled by default in the base device tree and are
intended to be enabled and extended via device tree overlays.

Note that a few components physically present on the SoM were omitted
from this description due to a lack of upstream bindings and drivers:
- Pressure Sensor
- V2X DSRC Radio
- Secure Element
