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: 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges")
Fixes: 266423e60ea1 ("pinctrl: bcm2835: Change init order for gpio hogs")

Hi SoC maintainers, please apply this directly for fixes, the
missing patch is wreacking havoc in the RPi world.

Now that "pinctrl: bcm2835: Change init order for gpio hogs" is in
Linus' master this patch can go in... what a mess, let's not do this again.

this patch has been send to soc@kernel.org in order to fix a regression
[1] caused by "pinctrl: bcm2835: Change init order for gpio hog". Would
be great to get it into 5.16

Yeah, my bad -- I only scanned for pull requests and missed this
patch. I'll send it up. Linus just merged the pull request I sent so
I'll do an incremental one.
