[WHY&HOW] DCN401 uses a different structure to store the VStartup offset used to calculate the VUpdate position, so adjust the calculations to use this value.

This one was reverted upstream by: commit 0fc9635a801f6ba3a03ad2de6d46f4f3e2fdfed6 Author: Dillon Varone Dillon.Varone@amd.com Date: Fri Mar 28 12:56:39 2025 -0400

Revert "drm/amd/display: Fix VUpdate offset calculations for dcn401"

This reverts commit fe45e2af4a22e569b35b7f45eb9f040f6fbef94f.

Reason for revert: it causes stuttering in some usecases.

thanks,
