For blizzard, pl110 and tc6393xb this is harmless, but for pxa2xx Coverity noticed that it is used inside an "if" statement. Fix it because it's the file with the highest number of defects in the whole QEMU tree! Use "do...while (0)", or just remove the semicolon if there's a single statement in the macro.
