NAK. Sorry Arnd, you're worringly wrong on this.
secondary_startup will do the setend if necessary, there's no need
to do this kind of junk in each and every platform. It's been this
way since:
commit 97bcb0fea590d3d704f985bec08f342d28992634

So, I hope you've not been telling platform folk to do this. Please
audit the arm-soc code to make sure, thanks.
