arm64: dts: freescale: add Toradex SMARC iMX95 

Add DT support for Toradex SMARC iMX95 SoM and Development carrier
board.

The module consists of an NXP i.MX95 family SoC, up to 16GB of LPDDR5
RAM and up to 128GB of storage, a USB 3.0 Host Hub and 2.0 OTG, two
Gigabit Ethernet PHYs, a 10 Gigabit Ethernet interface, an I2C EEPROM
and Temperature Sensor, an RX8130 RTC, a Quad/Dual lane CSI interface,
and some optional addons: TPM 2.0, DSI, LVDS, DisplayPort (through a
DSI-DP bridge), and Wi-Fi/BT module.
