[PATCH v9 7/8] pwm: pca9685: Restrict period change for enabled PWMs

Previously, the last used PWM channel could change the global prescale setting, even if other channels are already in use. Fix it by only allowing the first enabled PWM to change the global chip-wide prescale setting. If there is more than one channel in use, the prescale settings resulting from t
