[PATCH v3 2/4] can: Kconfig: change CAN_DEV into a menuconfig

[Vincent Mailhol <mailhol.vincent@wanadoo.fr>]

Currently, only slcan, vcan and vxcan do not depend on CAN_DEV. This
is going to change in the next patch when can_dropped_invalid_skb()
will be moved into skb.c.

In prevision to that, move CAN_DEV one rank up by making it a
menuconfig. The description of CAN_DEV is updated accordingly.
