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' |
	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

4ae72db135 net: Enable PM settings on network devices 
By changing the various *NET_DEVICE* macros. It is up to the device
drivers to either set a proper PM function or, if not supported or PM
disabled, to use device_pm_control_nop relevantly.

All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.

79ed6a7e53 drivers: can: loopback: Use thread to send frames. 
The loopback driver is a simple driver that can be used to
test CAN subsystems. The actual implementation sends frames
in the same thread that calls the send function.
Some libraries have problems with that behavior.
This PR implements a dedicated thread that calls the callback
for the receiving functions and a msgq in between the sender
and the TX thread.

c0da8a7901 drivers: can: Extend CAN API for bus-state management. 
This commit extends the CAN API with the following functions:
- can_get_state
- can_recover
- can_register_state_change_isr

This functions can be used to get the error-counters and the state
of the CAN controller. The recover function can be used to recover
from bus-off state when automatic recovery is disabled.
