arm64: dts: renesas: rzg3e-smarc-som: Reduce I2C2 clock frequency
Lower the I2C2 bus clock frequency on the RZ/G3E SMARC SoM from 1MHz to 400kHz to improve compatibility with a wider range of I2C peripherals. As the GreenPAK device is programmed to operate at 400kHz, the previous 1MHz setting was too aggressive, causing it to experience timing issues.
