drivers: can: deprecate the can_attach_workq() API call

Browse source 
Deprecate the can_attach_workq() API call.

This API is limited in its functionality (it does not work with
userspace, it uses one common buffer size for all work queue instances).

Similar functionality can easily be implemented using the
can_attach_msgq() API along with the generic triggered work API
(e.g. using k_work_poll_submit()).
