arm/highbank: Fix CBAR initialisation
Fix the CBAR initialisation by using the newly defined static property.
CBAR is now set before realization, so the intended value is now
actually used.
So I have kind of tested this. I booted an ARM kernel on Highbank with
the stock Highbank DTB. It doesn't boot (and I will be doing something
wrong), but before this patch I got this:

Which disappears with this patch.
