[DPU PATCH v2 06/14] drm/msm/dpu: remove stale encoder code

[Sravanthi Kollukuduru]

From: Jeykumar Sankaran <jsanka at codeaurora.org>

Remove helper function used only by writeback
connectors to trigger final flush before disabling.
Now that write back connectors are stripped down,
the helper is not used.

changes in v2:
     - none
