drm/amd/display: Explicitly specify update type per plane info change
[ Upstream commit 710cc1e7cd461446a9325c9bd1e9a54daa462952 ]
[Why]
The bit for flip addr is being set causing the determination for
FAST vs MEDIUM to always return MEDIUM when plane info is provided
as a surface update. This causes extreme stuttering for the typical
atomic update path on Linux.
[How]
Don't use update_flags->raw for determining FAST vs MEDIUM. It's too
fragile to changes like this.
Explicitly specify the update type per update flag instead. It's not
as clever as checking the bits itself but at least it's correct.
