Subject: dtc: Fix recognition of whitespace characters

From: David Gibson <[email-masked]>

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.
