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.
