Subject: [PATCH] ARM: dts: imx7ulp: Correct gpio ranges

Correct gpio ranges according to i.MX7ULP pinctrl driver:

gpio_ptc: ONLY pin 0~19 are available;
gpio_ptd: ONLY pin 0~11 are available;
gpio_pte: ONLY pin 0~15 are available;
gpio_ptf: ONLY pin 0~19 are available;

Fixes: 20434dc92c05 ("ARM: dts: imx: add common imx7ulp dtsi support")
