As CAN FD is already supported by SocketCAN on Linux, just enable the
fdcan pseudomodule and allow CAN FD frames.

RIOT implementation of CAN bus relies on SocketCAN model.
Since commit c398e56 (can: add optional DLC element to Classical CAN
frame structure), '__u8 can_dlc' attribute of struct can_frame is
considered as deprecated in SocketCAN and kept for legacy support.
Attribute '__u8 len' should be used instead.
union {
/* CAN frame payload length in byte (0 .. CAN_MAX_DLEN)
* was previously named can_dlc so we need to carry that
* name for legacy support
*/
__u8 len;
__u8 can_dlc; /* deprecated */
};
Moreover, CAN FD frame structure does not support legacy attribute
'can_dlc', making 'len' mandatory for incoming CAN FD support in RIOT.
struct canfd_frame {
canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
__u8 len; /* frame payload length in byte */
__u8 flags; /* additional flags for CAN FD */
__u8 __res0; /* reserved / padding */
__u8 __res1; /* reserved / padding */
__u8 data[CANFD_MAX_DLEN]
__attribute__((aligned(8)));
};

b4f29035ce6ee12949df1227ee463340ea8e8571 adapted the can_linux module to
the periph_can interface. This is a cleanup of some things that stayed
behind. Here the makefile is removed, the references to can_linux in the
dependency resolution and configuration Makefile are changed to the
standard periph_can, and the startup code is adapted.
Native CAN device was not properly ported to periph_can interface.
This commit fixes this by renaming all needed structures and files so
auto_init_can can initialize the native device. FEATURES_PROVIDED is
also updated for native.
