dtc: Fix recognition of whitespace characters
At present, the lexer in dtc recognizes only space, tab and newline as whitespace characters. This is broken; in particular this means that dtc will get syntax errors on files with DOS-style (CR-LF) newlines. This patch fixes the problem, using flex's built-int [:space:] character class.
