CTL datapath idx can be switched between secondary and external displays as per current SW code. This change avoids the clearing the SW flush ctx in prepare_commit during resume use case. It fixes the GPU fence timeouts seen during below scenario. Issue scenario: 1. Primary display was using CTL_0 and it is reserved. 2. Secondary display was using CTL_1 and suspend occurred. CTL_1 is added to RM free list. 3. When external Display is connected, it starts using CTL_1 datapath. 4. Secondary display is resumed and it starts using CTL_2. During prepare_commit, phys_enc->hw_ctl was CTL_1 and SW is clearing the flush ctx of external Display. 5. Since CTL_1 flush bits are cleared, SW is not programming the CTL_FLUSH register for this composition and release/retire fences are not signaled causing fence timeouts at GPU end and Input fence timeout at display end finally leading to SF hung.
