PATCH 1/1 dtc: Improve portability

1) Remove the double parentheses around two comparisons in checks.c. The OSX LLVM-based C compiler warns about them.
2) Put an explicit "=" in the TN() macro, in accordance with c99.

That seems a weird thing to warn for, but the result is cleaner anyway, so I'm happy to apply it.

I'm slightly astonished that ever worked.

I need a Signed-off-by line, then I can apply.
