Timer Blink (GPT1)

An original CC0 bare-metal i.MX RT1062 program. It gates GPIO and GPT1 in CCM, configures pin 13 as an output, programs the GPT1 prescaler (PR) and output-compare (OCR1), starts the counter (CR.EN in restart mode), then polls the output-compare flag (SR.OF1) and toggles the LED once per timer period. Exercises the real GPT1 counter/prescaler/compare path.
