The GPIO driver for the Intel Apollo Lake has so many pins it has to
export ten devices to shoehorn its one device into the GPIO API. The
current implementation uses the shared IRQ driver because these
pseudodevices all share one IRQ. However, since the GPIO driver is
aware of all the possible interrupt sources, it's smaller and faster
(and not even messy) to handle it internally, so this patch eliminates
the dependency on the shared IRQ driver.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h

Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

Some mcux gpio instances do not have dedicated interrupt vectors and
therefore conditionalize out the IRQ_CONNECT() and irq_enable() calls
during driver initialization. The driver initialization incorrectly
returned an error in this case, when really it just has nothing to do.
The driver can still be used without interrupts, and the gpio configure
function returns an error if an application tries otherwise.
Commit a68120de6d introduced a check on
the init return value to prevent applications from using drivers that
fail to initialize. This in turn caused zephyr/samples/basic/threads to
assert on the frdm_kl25z board. Fix this by modifying the mcux gpio
driver to return success when there is no interrupt to connect.

This allows the shared_irq driver to be configured by device tree.

The iterator over registered callbacks failed to account for the
possibility that the callback would remove itself from the list. If
this occurred any remaining callbacks would no longer be reachable from
the node. Switch to the slist iterator that is safe for self-removal.
Note that the slist API remains unsafe for removal of subsequent nodes.
Even with the corrected code removal of the next callback registration
(cached in tmp) will result in it being called anyway, with the
remaining unremoved registrations not being called. If the next
callback were removed and re-registered on a different device, the
callbacks would be invoked for the wrong device.
Resolve this by a documentation change describing the conditions under
which a change to callback registration from within a callback are
permitted. Add a similar note regarding the effect of adding a
callback. The current event invocation behavior for callbacks added
within an event is explicitly left unspecified, though in the current
slist implementation newly added callbacks will not be invoked until the
next event.

Behavior of function gpio_stm32_configure has been modified
during driver factorization. Various gpio settings (speed, mode, ..)
are applied conditionally while they used to be applied in sequence,
unconditionally before this change. As a consequence some
combinations of configurations are no more applied (like speed for
alternate mode). This of course has impact in some use cases.
Rework functions in order to apply settings unconditionally. Take
advantage of the change to reduce code size.
This change impacts all SoCs except F1 series.
