Some applications turn logging off. It makes impossible to get information about exceptions if it occures. This PR restores correct behavior of Error_Dump messages, and exception dump is printed anyway independent on CONFIG_LOG. ARC_EXCEPTION_DEBUG added to default boards configs in addition to nsim. CONFIG_FAULT_DUMP removed from ARC branch as it has been unused since v1.8.0 Signed-off-by: Nikolay Agishev <agishev@synopsys.com>
