mb/google/kohaku: Adjust I2C clock frequency

All serial I2C bus frequencies should not be over 400KHz in kohaku,
but the measurement showed frequencies of I2C1 and I2C4 were over
400KHz. (b:144885961)

This change adjusts I2C speed settings to limit that frequencies to
400KHz.

The new setting values have been from other projects using same I2C
components, and verified I2C1 and I2C4 frequencies < 400MHz internally.

BUG=b:144885961
BRANCH=firmware-hatch-12672.B
TEST=Verified I2C1 and I2C4 frequency not over 400KHz
