Subject: [PATCH 1/2] ARM: dts: stm32: Add gpio-ranges for stm32f746-pinctrl

From: Patrice Chotard <patrice.chotard@...s.st.com>

Since commit 913a956c4363 ("pinctrl: stm32: use dynamic allocation
of GPIO base"), it's impossible to retrieve gpios from phandle,
for example, mmc driver can't retrieve cd-gpios.
Add missing gpio-ranges properties to fix it.
