The reset button on imx8mm-evk is tied to PWRON_B pin of bd71847 and the long press duration is set to zero from OTP. The linux driver overrides those values and breaks reset from button. Overwriting OTP or bootloader configuration with some hardcoded defaults is not desirable, power button should behave identically from bootloader to kernel. Add DT properties to allow explicitly overriding press durations but don't do anything by default.
