Linux-4.12 doesn't yet enter rc1, and the defines are still not in
Linus's tree.

Please note that I have already mentioned that this patch is necessary
to be merged into 4.12, otherwise poweroff won't work properly at 4.12 .

So I think it shouldn't still use defines.

I will fix here after 4.12-rc1 is out, along with other r_ccu
usages.
