mb/google/volteer/variants/volteer2: Tune Volteer2 I2C2 bus frequency
The current I2C2 bus frequency is 344 kHZ, which does not meet the spec. This change updates scl_lcnt, scl_hcnt, sda_hold value for I2C2 to bring
the bus frequency closer to 400 kHz.
BUG=b:153588771
TEST=Verified that I2C2 frequency is 380 kHz.
