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

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
)

expression E;
@@
(
net_if_get_device(E)->

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' |

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

Fixes #27397

86bfc489f4 scripts: Replace hard-coded subsystem list with __subsystem annotations. 
This change removes the hardcoded subsystem list in gen_kobject_list.py
favor of marking the relevant driver API structs with the _subsystem
sentinel.

13b8b41676 drivers: watchdog: add system calls 
wdt_install_timeout() was skipped as it installs an ISR-context
callback handler function. The rest are simple wrappers.

Added myself as the maintainer of the syscall handlers. WDT
subsystem appears to not currently have an owner.

Fixes: #21432
