Paul Cercueil a6030d71e6 pwm: jz4740: Enhance precision in calculation of duty cycle
commit 9017dc4fbd59c09463019ce494cfe36d654495a8 upstream.

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)
