mb/google/volteer/variant/volteer: Turn I2C3 bus freq closer to 400 kHz for camera

The current I2C3 bus frequency is 341 kHZ, which does not meet the spec. This change updates scl_lcnt, scl_hcnt, sda_hold value for I2C3 to bring the bus frequency closer to 400kHz.

BUG=b:153588771 TEST=Verified that I2C3 frequency is 394kHz.
