dtc: Trivial lexer cleanups
From: David Gibson <hidden>

This patch applies a couple of tiny cleanups to the lexer. The not-very-useful 'WS' named pattern is removed, and the debugging printf() for single character tokens is moved to the top of the action, which results in less confusing output when LEXDEBUG is switched on (because it goes before the printf()s for possible resulting lexer state changes).
