mb/google/deltaur: Change H1 I2C speed to STANDARD
Currently, Deltaur’s I2C speed has not been tuned yet, so slow down the H1 I2C to avoid I2C error for short term. Error logs: Reading cr50 TPM mode I2C receive timeout I2C read failed: bus 3 addr 0x50 BUG=b:154310066 TEST=Check H1 has no I2C error occurring and can be updated by gsctool.
