arm64: dts: freescale: Add Verdin iMX95 support

Add support for the Toradex Verdin iMX95 and its development carrier
board.

The module consists of an NXP i.MX95 family SoC, up to 16GB LPDDR4x RAM,
up to 128GB of storage, a USB 3.2 OTG and USB 2.0 Host, a Gigabit
Ethernet PHY, an I2C EEPROM and Temperature Sensor, an RX8130 RTC, an
I3C bus, one Quad lane CSI interface, one Quad lane DSI or CSI
interface, one LVDS interface (one or two channels), and some optional
addons: TPM 2.0, and a WiFi/BT module.
