    tegra124: Add a macro specifically for configuring the I2C controller clocks.
    
    The divider for the I2C clocks works differently than for other IP blocks and
    needs to be set up to reflect that. There's also a large internal divider which
    means you have to do extra calculations to determine what the frequency of the
    bus itself will be based on the I2C controller clock. The new macro takes the
    desired frequency of the bus itself and figures everything else out.
    
    BUG=chrome-os-partner:25467
    TEST=Built and booted on nyan rev1 using this function to set up the i2c
    busses.
    BRANCH=None
