Introducing i2c-clk-duty-cycle-min property for setting minimum persentage of clock high. This driver will go through base clock divisor and calculate a set of high/low clock with duty cycle applied. if driver could not find a suit high/low clock set, then it will use default duty cycle (50%) recalculate.
