    broadwell: Increase I2C SDA hold timing to 300ns
    
    I2C bus SDA hold time can be marginal with 60ns value, especially
    when there is level shifter on the bus. So program it to 300ns
    based on Fast-mode specification, which is between 0 to 900ns.
    Apply the same timing for Standard-mode as well.
    
    Refer to original bug on BayTrail chrome-os-partner:28092, this
    is to carry forward the fix to Broadwell.
