samples: blinky_pwm: decreased min PWM period for blinky sample

Browse source 
Blinky PWM sample minimum pwm period was too high for iMX.RT PWM module.
decrease the minimum pwm period so sample will pass pwm calibration
phase.

Fixes #38954

@ -11,7 +11,7 @@ This application blinks a LED using the :ref:`PWM API <pwm_api>`. See
:ref:`blinky-sample` for a GPIO-based sample.
The LED starts blinking at a 1 Hz frequency. The frequency doubles every 4
seconds until it reaches 64 Hz. The frequency will then be halved every 4
seconds until it reaches 128 Hz. The frequency will then be halved every 4
seconds until it returns to 1 Hz, completing a single blinking cycle. This
faster-then-slower blinking cycle then repeats forever.
