can: Kconfig: turn menu "CAN Device Drivers" into a menuconfig using CAN_DEV

Browse Source 
In the next patches, the software/virtual drivers (slcan, v(x)can)
will depend on drivers/net/can/dev/skb.o.

This patch changes the scope of the can-dev module to include the
above mentioned drivers.

To do so, we reuse the menu "CAN Device Drivers" and turn it into a
configmenu using the config symbol CAN_DEV (which we released in
previous patch). Also, add a description to this new CAN_DEV
menuconfig.

The symbol CAN_DEV now only triggers the build of skb.o. For this
reasons, all the macros from linux/module.h are deported from
drivers/net/can/dev/dev.c to drivers/net/can/dev/skb.c.

Finally, drivers/net/can/dev/Makefile is adjusted accordingly.
