GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.
For the details one may look into the of_gpio_dev_init() implementation.
While at it, remove duplicate parent device assignment where it is the case.

Casting a pointer to u16 can produce a compiler warning such as this:
drivers/gpio/gpio-ge.c: In function 'gef_gpio_probe':
drivers/gpio/gpio-ge.c:83:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
gc->ngpio = (u16)of_device_get_match_data(&pdev->dev);
^
Cast the pointer through a uintptr_t to avoid the warning.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Use devm_gpiochip_add_data() for GPIO registration.

The separate struct bgpio_chip has been a pain to handle, both
by being confusingly similar in name to struct gpio_chip and
for being contained inside a struct so that struct gpio_chip
is contained in a struct contained in a struct, making several
steps of dereferencing necessary.
Make things simpler: include the fields directly into
<linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and
get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix
some of the member variables with bgpio_* and add proper
kerneldoc while we're at it.
Modify all users to handle the change and use a struct
gpio_chip directly. And while we're at it: replace all
container_of() dereferencing by gpiochip_get_data() and
registering the gpio_chip with gpiochip_add_data().

The GE GPIO driver provides basic support (set direction, read/write state)
for the GPIO provided on some GE single board computers. This patch moves
the driver from the 86xx specific platform directrory to the GPIO subsystem
so that it can be used on non-86xx boards.
