7b04f98027 gpio: bcm-kona: make irq_chip immutable 
The gpiolib is moving to make irq_chip immutable, otherwise
there is warning: "not an immutable chip, please consider fixing it!"

The bcm_gpio_irq_chip already has irq hooks configured correctly,
bcm_kona_gpio_irq_mask/bcm_kona_gpio_irq_unmask calls gpiochip_disable_irq/
gpiochip_enable_irq, and bcm_kona_gpio_irq_reqres/irq_release_resources
calls gpiochip_reqres_irq/gpiochip_relres_irq.

So just need to  flag it as IRQCHIP_IMMUTABLE.

833c086f22 gpio: TODO: add item about GPIO drivers reading struct gpio_chip::base 
drivers/pinctrl/pinctrl-at91.c uses struct gpio_chip::base to find out
which bit to set in a register:

  dev_dbg(npct->dev, "enable pin %u as GPIO\n", offset);

  mask = 1 << (offset - chip->base);

This adds a non-obvious dependency on the global numberspace from the
GPIO driver itself, even if all consumers use the descriptor API.

More such instances may exist and will need to be fixed in the quest for
removal of the global numberspace, so add a reminder about it to the
TODO list.

0a45c1a002 gpio: mxc: configure dynamic GPIO base for CONFIG_GPIO_SYSFS=n 
i.MX GPIO numbering has been deterministic since commit 7e6086d9e5
("gpio/mxc: specify gpio base for device tree probe"), a year after
device tree support was first added back in 2011.

Reverting to dynamically allocated GPIO base now would break most
systems making use of the sysfs API. These systems will be eventually
broken by the removal of the sysfs API, but that would result in GPIO
scripts not working instead of essentially toggling at random according
to probe order, which would happen if we unconditionally set base to -1.

Yet, the warning is annoying and has resulted in many rejected attempts
to remove it over the years[1][2][3].

As the i.MX GPIO driver is device tree only, GPIO_SYSFS is the only
consumer of the deterministic GPIO numbering. Let's therefore restrict the
static base and the warning that comes with it to configurations
with CONFIG_GPIO_SYSFS enabled.

The GPIO and NVMEM interfaces are accessed via specific commands to the
