Extra message added for hardware initialization failure. Such common issues are mostly caused by wrong wiring. Message about success added as well, it should be useful to debug new hardware configuration, especially in case of several CAN buses.

This patch adds this support. This driver configures the controller to halt on bus-off entry. Hence, when in error states less than bus off state, the TEC/REC counters are checked for lower state transition eligibility and action.
