Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Tomasz Bursztyka 98d9b01322 device: Apply driver_api/data attributes rename everywhere 
Via coccinelle:

@r_device_driver_api_and_data_1@
struct device *D;
@@
(
D->
-	driver_api
+	api
|
D->
-	driver_data
+	data
)

@r_device_driver_api_and_data_2@
expression E;
@@
(
net_if_get_device(E)->
-	driver_api
+	api
|
net_if_get_device(E)->
-	driver_data

And grep/sed rules for macros:

git grep -rlz 'dev)->driver_data' |
	xargs -0 sed -i 's/dev)->driver_data/dev)->data/g'

git grep -rlz 'dev->driver_data' |
	xargs -0 sed -i 's/dev->driver_data/dev->data/g'

git grep -rlz 'device->driver_data' |
	xargs -0 sed -i 's/device->driver_data/device->data/g'

Fixes #27397

Peter A. Bigot 8328159b09 include: respect line limit in api pointer initialization 
The automated process used to remove implicit casts resulted in code
that exceeded the documented line length limits.  Break the assignment
into two lines where this happened.

Peter A. Bigot 2e358f11d0 include/drivers: remove implicit casts from api pointer initialization 
C++ disallows implicit cast of void pointers to a non-void pointer
type.  Presence of implicit casts prevents use of these headers in C++
applications.

Process: Run the following coccinelle script:

@@
identifier V;
identifier TAG =~ "driver_api";
type T;
expression E;
@@
 T* V =
+(T *)
 E->TAG;

in this command line from $ZEPHYR_BASE:

spatch --sp-file expcast.cocci \
   --include-headers --dir include/ --very-quiet \
 | sed -e '/^\+/s@\*) @*)@' \
 | (cd include/ ; patch -p1)

Rajavardhan Gundi 74016bb64c drivers: interrupts: introduce CAVS interrupt logic 
CAVS interrupt logic is an intel IP that combines several sources of
interrupt into one line that is then routed to the parent controller.
CAVS stands for "connected Audio, Voice and Speech". This IP supports
4 lines which can have a max of 32 interrupts each.
