arm64: dts: freescale: Add support for i.MX8QXP AI_ML board

Add support for i.MX8QXP AI_ML board from Einfochips. This board is one
of the Consumer Edition boards of the 96Boards family based on i.MX8QXP
SoC from NXP/Freescale.

The initial support includes following peripherals which are tested and
known to be working:

1. Debug serial via UART2
2. uSD
3. WiFi
4. Ethernet
