google/eve: Set touchscreen I2C bus speed to 1MHz

Enable Fast-Plus speed for the touchscreen device so it can
    be used at 1MHz instead of 400KHz.

BUG=chrome-os-partner:61277
    TEST=manual testing on Eve P1, needs backported kernel patches
    to actually make use of any I2C speed other than 400KHz
