Paul Cercueil 9017dc4fbd pwm: jz4740: Enhance precision in calculation of duty cycle 
Calculating the hardware value for the duty from the hardware value of
the period resulted in a precision loss versus calculating it from the
clock rate directly.

(Also remove a cast that doesn't really need to be here)
