add cpu.h from linux:

7538ec7d1e5: ARM: at91: remove no-MMU at91x40 support

so it is easier to port linux code, which is based on it.

My comment still holds, you should not need that a no Linux code is
using cpui_is_at91* anymore. The main concern is that you will be based
on an older version of the driver and you will be missing future fixes.

Sorry, seems I missed your comment ... Sorry for that.

Ok, I look into this, and update to a newer version.
