From: Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>

Set kaddr1 from res.a1 when the configuration status completes, matching
the existing error path and allowing callers to retrieve firmware-returned
status details through the standard kaddr1 interface.

Signed-off-by: Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>

Changes in v2:
- Drop the callback-data lifetime / dangling-pointer changes.
- Reduce the series to this standalone patch. Set kaddr1 with &res.a1
  on the completed path, matching the existing error path.
