Description

#5256 Fixed the crash in mpl2;
#5255 Solved the problem of mpl2 not completing due SA not finding a valid tiling for the root.

However, even though mpl2 flow finishes there's a huge deterioration in WL.

Suggested Solution

Use only constrained pin data for IO Pins in mpl2 flow so that hierarchical macro placement SA can find a better floorplan.
