can: Kconfig: rename config symbol CAN_DEV into CAN_NETLINK

In the next patches, the scope of the can-dev module will grow to
engloble the software/virtual drivers (slcan, v(x)can). To this
extent, release CAN_DEV by renaming it into CAN_NETLINK. The config
symbol CAN_DEV will be reused to cover this extended scope.

The rationale for the name CAN_NETLINK is that netlink is the
predominant feature added here.

The current description only mentions platform drivers despite the
fact that this symbol is also required by "normal" devices (e.g. USB
or PCI) which do not fall under the platform devices category. The
description is updated accordingly to fix this gap.
