As only second scaler can be used for sharpness check if it
is available and also check if panel fitting is also not enabled,
then set the sharpness. Panel fitting will have the preference
over sharpness property.
v2: Add the panel fitting check before enabling sharpness
v3: Reframe commit message[Arun]
v4: Replace string based comparison with plane_state[Jani]
