ARM: dts: gpio-ranges property is now required
[ Upstream commit c8013355ead68dce152cf426686f8a5f80d88b40 ]
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.

pin-ranges")
