 PICO-PI-IMX8M

Sorry for top posting. I'm replying using mobile phone and outlook web app... 

gpio_intr is not needed. Irq must be given using the standard irq property. gpio_intr has been used in an old draft driver - I assume the dts originates from NXP bsp which used the old driver.

I do not see property 'gpio_intr' in there.
