drm/amd/display: calculate final viewport before TAP optimization

Browse source

[ Upstream commit e982310c9c ]

Viewport size excess surface size observed sometime with some timings or
resizing the MPO video window to cause MPO unsupported. Calculate final
viewport size first with a 100x100 dummy viewport to get the max TAP
support and then re-run final viewport calculation if TAP value changed.
Removed obsolete preliminary viewport calculation for TAP validation.
