[PATCH v1 7/7] arm64: dts: freescale: imx95-verdin: Add Zinnia

[Francesco Dolcini <francesco@dolcini.it>]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add Zinnia Carrier Board mated with Verdin iMX95.

It features 1 x RS232, 1 x RS485, 1 x CAN, 3 x isolated digital I/O,
2 x GBit/s Ethernet, a mini PCIe slot with USB / SIM card connector
for a modem, USB and SD card interfaces.
