MLK-17491-13 dts: imx7ulp: improve the gpio using
Currently people have no idea on which pad is correspding to which gpio
controller as there's no hints in dts. Let's add a proper prefix for gpio
nodes as follows in dts to make it much easier to use.
gpio0 = &gpio_ptc;
gpio1 = &gpio_ptd;
gpio2 = &gpio_pte;
gpio3 = &gpio_ptf;
