In reviewing this change as part of some ASPEED device tree changes,
we moved the define out of this header (as we do not want it to be
part of the ABI) and into the c file where it is used.

I have a v7 ready to send out with this change. Are there any other
issues with this before I send that version out?

Cheers,

Joel
