i2c: qcom-geni: Update i2c frequency table to match hardware guidance
With the current settings, the I2C buses are achieving around 370KHz instead of the expected 400KHz. For 100KHz and 1MHz, the settings are now more compliant and adhere to the Qualcomm’s internal programming guide. Update the I2C frequency table to align with the recommended values outlined in the I2C hardware programming guide, ensuring proper communication and performance.
