pwm: imx: Don't drop the enable bit once set

Changing the duty-cycle should not blindly override (and clear) the
enable (EN) bit if it has already been set. For instance, a PWM
backlight can be enabled and set to a specific intensity using two
operations. The order of these operations should not matter.
