This change also includes the following FCM cleanups:
- Adds level="6", specifying that this product FCM is compatible with an
S vendor image. This is similar to the framework FCM.
- Marks the HAL as required. This is possible now that the redfin_vf
target includes an additional product FCM specific to level="5" (R).
