NOT TESTED, REVIEW CAREFULLY.

This series cleans up technical debt in the ISP configuration path of
the AtomISP driver.

Resolves a long-standing FIXME by gating ref and TNR frame configuration
behind the ISP feature flags that already govern their allocation,
rather than unconditionally attempting to use frames that may not have
been built into the pipeline, and removes a duplicate call that
overwrites the same cached state with identical values.

v2:
- Replaced NULL checks with feature flag guards to address the root
  cause rather than the symptom.
- Updated subject line and commit message accordingly in patch 1/2.
- Expanded commit message to explain why the duplicate call is safe to
  remove in patch 2/2.
- Updated subject line in patch 2/2.
