Larry Johnson 7754f33c6f LM73 bug fix for negative temperatures and cleanup 
When the LM73 temperature sensor measures a temperature below 0 C, the
current driver does not perform sign extension, so the result returned is
512 C too high.  This patch fixes the problem, and does general cleanup
of the code.
