Add support for ifm i.MX8MN VHIP4 EvalBoard v1 and v2 reference design.
This system exists in two generations, v1 and v2, which share a lot of
commonality. The boards come with either single gigabit ethernet or an
KSZ8794 fast-ethernet switch, boot from eMMC, and offer CAN interfaces
via Microchip MCP25xx SPI CAN controllers, UART, and USB host. The GPU
is not available in the SoC populated on these devices.
