drm/msm/dpu: separate DSC flush update out of interface
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.
Changes in v10:
-- rewording commit text
-- pass ctl directly instead of dpu_enc to dsc_pipe_cfg()
-- ctx->pending_dsc_flush_mask = 0;
Changes in v11:
-- add Fixes tag
Changes in v12:
-- move dsc parameter to next line at dpu_encoder_dsc_pipe_cfg()
Changes in v14:
-- Fixes tag had been move to 1st patch of this series
