[PATCH v1 2/3] arm64: dts: freescale: Add support for Variscite VAR-SMARC-MX8M-PLUS

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

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

Add device tree support for the Variscite VAR-SMARC-MX8M-PLUS system on
module. This SOM is designed to be used with various carrier boards.

The module includes:
- NXP i.MX8M Plus MPU processor
- Up to 8GB of LPDDR4 memory
- Up to 128GB of eMMC storage memory
- Two integrated 10/100/1000 Mbps Ethernet transceivers
- WM8904 audio codec
- Dual-band Wi-Fi 6 and Bluetooth
- USB 3.0 hub
- GPIO expander
- RTC, EEPROM and ST33 TPM

Only SOM-specific peripherals are enabled by default. Carrier board
specific interfaces are left disabled to be enabled in the respective
carrier board device trees.
