drm/amd/display: Update optimized blank calc and programming

Browse source

[Why]
The existing calculations in DCN3.1 were placeholder and need to be
replaced with HW team approved calculations.

[How]
The new calculations add new parameters to the bounding box and pipe
params - VblankNom and the bounding box default.

The placeholder calculations are dropped from DCN3.1 in the meantime
while we work out hardware approved replacements.
Also fix a bug where we wipe out other register contents with a REG_SET
instead of a REG_UPDATE for the register we were programming the
min_dst_y_next_start_optimized.
