can: propagate CAN device capabilities via ml_priv
Commit 1a620a723853 ("can: raw: instantly reject unsupported CAN frames")
caused a sequence of dependency and linker fixes.
Instead of accessing CAN device internal data structures which caused the
dependency problems this patch introduces capability information into the
CAN specific ml_priv data which is accessible from both sides.
With this change the CAN network layer can check the required features and
the decoupling of the driver layer and network layer is restored.
