6defabebad drivers: can: Fix building with socket_can_generic.h 
socket_can_generic.h makes some assumptions that are not always valid
for various drivers with regards to numbering.  To clean this up we
add defines for SOCKET_CAN_NAME_0 and SOCKET_CAN_NAME_2 in addition to
SOCKET_CAN_NAME_1.

We also move struct socket_can_context into the drivers themselves
since they know best how many CAN interfaces are getting supported and
what naming/number convention they'd have.

Additionally, this also exposes a few other build issues with the
can_mcux_flexcan driver that get fixed.

Finally, we remove the platform_allow from samples/net/sockets/can
since it is no longer needed.

Fixes #31733

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

@@
(
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

06b500b6bd net: sockets: can: Close the socket cleanly 
If the socket is closed, then do CAN detach if that is needed.
This way the CAN interrupts are not received if there are no
CAN sockets listening the data.

b3b43b8921 drivers: can: Extend can_send with void *arg and pass it to the isr cb 
This commit extends the CAN api can_send function by an argument
that is passed to the isr callback.
With this extension it is possible to distinguish between sent masseges
when they use the same callback.
