2aed5a1237 drivers: can: remove CAN_BUS_UNKNOWN CAN controller state
The CAN_BUS_UNKNOWN CAN controller state is only used to indicate that
the current CAN controller state could not be read.

Remove it and change the signature of the can_get_state() API function
to return an integer indicating success or failure.

8af4bb722d drivers: can: rename API functions for better consistency
Rename a few CAN API functions for clarity and consistency with other
Zephyr RTOS APIs.

CAN_DEFINE_MSGQ() becomes CAN_MSGQ_DEFINE() to match K_MSGQ_DEFINE().

can_attach_isr() becomes can_add_rx_filter() since a filter callback
function is not an interrupt service routine (although it is called in
isr context). The word "attach" is replaced with "add" since filters are
added, not attached. This matches the terminology used is other Zephyr
APIs better.

can_detach() becomes can_remove_rx_filter() to pair with
can_add_rx_filter().

can_attach_msgq() becomes can_add_rx_filter_msgq() and documentation is
updated to mention its relationship with can_add_rx_filter().

can_register_state_change_isr() becomes can_set_state_change_callback()
since a state change callback function is not an interrupt service
routine (although it is called in isr context). The word "register" is
replaced with "set" since only one state change callback can be in
place.

b21a91e468 drivers: can: catch up on API naming changes
Catch up on the CAN driver API argument naming changes:
- Unify naming of callback function pointers as "callback".
- Unify naming of user-specified callback function arguments as
  "user_data".
- Instances and pointers to struct zcan_frame are named "frame",
  not "msg", to avoid confusion with the CAN message queue support.
