[PATCH stable 5.4 7/7] ARM: dts: gpio-ranges property is now required

[Florian Fainelli]

From: Phil Elwell <phil at raspberrypi.com>

commit c8013355ead68dce152cf426686f8a5f80d88b40 upstream

Since [1], added in 5.7, the absence of a gpio-ranges property has
prevented GPIOs from being restored to inputs when released.
Add those properties for BCM283x and BCM2711 devices.

[1] commit 2ab73c6d8323 ("gpio: Support GPIO controllers without
    pin-ranges")

Fixes: 266423e60ea1 ("pinctrl: bcm2835: Change init order for gpio hogs")
