The commit c8013355ea ("ARM: dts: gpio-ranges property is now required")
fixed the GPIO probing issues caused by "pinctrl: bcm2835: Change init
order for gpio hogs". This changed only the kernel DTS files. Unfortunately
it isn't guaranteed that these files are shipped to all users.
So implement the necessary backward compatibility for BCM2835 and
BCM2711 platform.

...and gpio-ranges
pinctrl-bcm2835 is a combined pinctrl/gpio driver. Currently the gpio
side is registered first, but this breaks gpio hogs (which are
configured during gpiochip_add_data). Part of the hog initialisation
is a call to pinctrl_gpio_request, and since the pinctrl driver hasn't
yet been registered this results in an -EPROBE_DEFER from which it can
never recover.
Change the initialisation sequence to register the pinctrl driver
first.
This also solves a similar problem with the gpio-ranges property, which
is required in order for released pins to be returned to inputs.

This reverts commit a49d784d5a.
The updated binding was wrong / invalid and has been reverted. There
isn't any upstream kernel DTS using it and Broadcom isn't known to use
it neither. There is close to zero chance this will cause regression for
anyone.
Actually in-kernel bcm5301x.dtsi still uses the old good binding and so
it's broken since the driver update. This revert fixes it.

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested. This is important for level triggered interrupts which need
to be masked during handling. Also, fix the interrupt acknowledge so
that it clears only one interrupt instead of all interrupts which are
currently active. Finally there is no need to clear the interrupt during
the interrupt handler, since the edge-triggered handler will do that for
us.

Leverage the IRQCHIP_MASK_ON_SUSPEND flag in order to avoid having to
specifically treat the GPIO interrupts during suspend and resume, and
simply implement an irq_set_wake() callback that is responsible for
enabling the parent wake-up interrupt as a wake-up interrupt.
To avoid allocating unnecessary resources for other chips, the wake-up
interrupts are only initialized if we have a brcm,bcm7211-gpio
