This is a driver so include only <linux/gpio/driver.h>.

Make this const as it is only used as a copy operation.
Done using Coccinelle.

The Kconfig currently controlling compilation of this code is:
drivers/gpio/Kconfig:config GPIO_ZEVIO
drivers/gpio/Kconfig: bool "LSI ZEVIO SoC memory mapped GPIOs"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.
This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:
@@
struct gpio_chip *var;
@@
-var->dev
+var->parent
and:
@@
struct gpio_chip var;
@@
-var.dev
+var.parent
and:
@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent
Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.
This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.

Since d621e8bae5ac9c67 (Create of_mm_gpiochip_remove), there is a
counterpart for of_mm_gpiochip_add.
This patch implements the remove function of the driver making use of
it.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

The spin_lock is required to ensure the direction is not changed before reading

This is a DT-only driver and it will be built only when CONFIG_OF is set.
So it's pointless to use of_match_ptr.
