Compared to SDM8450 DPU devices with active CTL support (SC7180, SM8x50) have merge support implemented in a separate hardware block, which is not supported at this point. Add support for dualpipe configuration on these platforms. Tested on Qualcomm RB5 (SM8250) platform.
Instead of calling 4 callbacks to set pending masks, call just one to update both pending_flush_mask and pending_intf_flush mask. Note, that CMD mode support incorrectly did not update pending_intf_flush mask, breaking CMD support on SC7180/SM8x50.
