riscv: dts: spacemit: k3: Initial support for CoM260-IFX board

Browse Source 
The K3 CoM260-IFX board combine with one 260 pins "Gold Finger" computer
module with a carrier board. The module integrates the K3 SoC, LPDDR5,
UFS storage, Gigabit Ethernet, Micro SD card, PMIC Chip. The board offers
a comprehensive array of interfaces, including MIPI-DSI, MIPI-CSI,
DisplayPort, SDIO, SPI, I2S, I2C, CAN-FD, PWM, UART, USB, PCIe, and GMAC.

Add initial support for enabling Serial UART and ethernet.
