hw/phb3: Update capi initialization sequence

The capi initialization sequence was revised in a circumvention
document when a 'link down' error was converted from fatal to Endpoint
Recoverable. Other, non-capi, register setup was corrected even before
the initial open-source release of skiboot, but a few capi-related
registers were not updated then, so this patch fixes it.

The point is that a link-down error detected by the UTL logic will
lead to an AIB fence, so that the CAPP unit can detect the error.
