The fix should be in a separate patch.

Currently DSC flushing happens during interface configuration at dpu_hw_ctl_intf_cfg_v1(). Separate DSC flush away from dpu_hw_ctl_intf_cfg_v1() by adding dpu_hw_ctl_update_pending_flush_dsc_v1() to handle both per-DSC engine and DSC flush bits at same time to make it consistent with the location of flush programming of other DPU sub-blocks.
