Bonus points for writing the test without "libqtest-single.h" and using only 
"libqtest.h" instead. We should try to avoid libqtest-single.h in new code 
since such code can not be shared with tests that run multiple instances of 
QEMU. But if it's too cumbersome, I do not insist.

Do you plan to add more aspeed tests later? If not, I think you could simply 
do it without this variable and use ['aspeed_hace-test'] below.
