CAN bus tests
This commit for testing CAN modules, sending and receiving frames, showing stats and and testing suitable bitrates for transmission.
The "test_can_loopback_mode" test can be run on a board with one interface.
This test will fail gracfully if the board dosen't have any CAN interface.
The other tests needs to be run on a board with two CAN interfaces (e.g. dra7 with external transceiver.)
These tests requires two interfaces on the same board to send frames with the first interface and to receive them with the other one
These tests will fail gracfully by skiping all test cases if the board doesn't have two interfaces.
