Oliver Hartkopp cb2dc6d286 can: Kconfig: select CAN driver infrastructure by default 
The CAN bus support enabled with CONFIG_CAN provides a socket-based
access to CAN interfaces. With the introduction of the latest CAN protocol
CAN XL additional configuration status information needs to be exposed to
the network layer than formerly provided by standard Linux network drivers.

This requires the CAN driver infrastructure to be selected by default.
As the CAN network layer can only operate on CAN interfaces anyway all
distributions and common default configs enable at least one CAN driver.

So selecting CONFIG_CAN_DEV when CONFIG_CAN is selected by the user has
no effect on established configurations but solves potential build issues
when CONFIG_CAN[_XXX]=y is set together with CANFIG_CAN_DEV=m

Fixes: 1a620a7238 ("can: raw: instantly reject unsupported CAN frames")
