[PATCH 3/5] drm/amd/display: Remove unused dc_stream_warmup_writeback

[linux at treblig.org]

From: "Dr. David Alan Gilbert" <linux at treblig.org>

dc_stream_warmup_writeback() is unused since it was added in 2019 by
commit 6a652f6d127d ("drm/amd/display: Add warmup escape call support")

Remove it.

Note there is a dcn30 version that's called directly which is kept.
