scripts/dtc/of_unittest_expect processes EXPECT messages that
document expected kernel messages triggered by unittest. Add
processing of EXPECT_NOT messages that document kernel messages
triggered by unittest that are not expected.
This is commit 2 of 2, implementing the processing of EXPECT_NOT
messages.
