Introducing i2c-clk-high-min-percent 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.

changes v3 --> v4:
* rename property to i2c-clk-high-min-percent
changes v2 --> v3:
* discard the properties for manual setting, use duty cycle to calculate
high/low clock.
changes v1 --> v2:
* update bt-bindings documentation
* use meaningful values for properties instead of acture value in register
