These i.MX SCU drivers depends on IMX_SCU, I already add the COMPILE_TEST
to IMX_SCU driver as well, that is why I put these patches in a patch series. Maybe
I can add stubs as well to make sure build passed even when IMX_SCU is NOT compiled?
Will send V2 to add stubs, it makes more sense.

Thanks,
Anson
