robert-hh e0b97013d0 mimxrt/hal/pwm_backport: Make PWM symmetric, and round division calcs.
Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been.  That is evident at high frequencies, like 15Mhz
or 37.5 MHz.  At low frequencies the deviation mattered less.  The A/B
channels were fine.

Also round up or down non-integer division factors. Before, always the
floor value was used.
