Convert the driver to immutable irq-chip with a bit of
intuition.

This driver require some special care: .irq_ack() was copied
from dummy_irq_chip where it was defined as noop. This only
makes sense if using handle_edge_irq() that will unconditionally
call .irq_ack() to avoid a crash, but this driver is not ever
using handle_edge_irq() so just avoid assigning .irq_ack().

A separate chip had to be created for the non-wakeup instance.

The OMAP1 at one point was using static irqs but that time is gone,
OMAP1 uses sparse irqs like all other multiplatform targets so this
static allocation of descriptors should just go.

Merge tag 'intel-gpio-v6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-gpio-intel into gpio/for-next

intel-gpio for v6.4-1

* Remove some of the legacy APIs that are not used anymore
* Clean up headers in the GPIO library and drivers

The following is an automated git shortlog grouped by driver:

aggregator:
 -  Add missing header(s)

ARM:
 -  s3c64xx: Use the right include
 -  orion/gpio: Use the right include

gpiolib:
 -  Clean up headers
 -  Group forward declarations in consumer.h
 -  Deduplicate forward declarations in consumer.h
 -  Drop unused forward declaration from driver.h
 -  split of_mm_gpio_chip out of linux/of_gpio.h
 -  split linux/gpio/driver.h out of linux/gpio.h
 -  remove legacy gpio_export()
 -  remove gpio_set_debounce()
 -  remove asm-generic/gpio.h
 -  coldfire: remove custom asm/gpio.h
 -  remove empty asm/gpio.h files
 -  Make the legacy <linux/gpio.h> consumer-only

hte:
 -  tegra-194: Use proper includes

reg:
 -  Add missing header(s)

regmap:
 -  Add missing header(s)

There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically

Now that coldfire is the only user of a custom asm/gpio.h, it seems
better to remove this as well, and have the same interface everywhere.

For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep()
functions, the custom version is only a micro-optimization to inline the
function for constant GPIO numbers. However, in the coldfire defconfigs,
I was unable to find a single instance where this micro-optimization
was even used, and according to Geert the only user appears to be the
QSPI chip that is disabled everywhere.

The custom gpio_request_one() function is even less useful, as it is
guarded by an #ifdef that is never true.

The arm and sh versions of this file are identical to the generic
versions and can just be removed.

The drivers that actually use the sh3 specific version also include
cpu/gpio.h directly, with the exception of magicpanelr2, which is
easily fixed. This leaves coldfire as the only gpio driver
that needs something custom for gpiolib.
