boards: Add Pico-Pi i.MX7D

Joris Offouga


I am new zephyr user and I try to integrate the Pico-Pi i.MX7D board, during my compilations, I have this warning :

warning: 'imx_gpio_driver_api' defined but not used [-Wunused-const-variable=]
 static const struct gpio_driver_api imx_gpio_driver_api = {
/home/jun/zephyr/drivers/gpio/gpio_imx.c:157:13: warning: 'imx_gpio_port_isr' defined but not used [-Wunused-function]
 static void imx_gpio_port_isr(void *arg)

But I do not use gpio in the example, I build correctly the hello_world example, the binary works well on the target but I will like the corrected for this PR :

Best regards
