drm/dp/mst: Calculate MST PBN with 31.32 fixed point Our PBN value overflows the 20 bits integer part of the 20.12 fixed point. We need to use 31.32 fixed point to avoid this. This happens with display clocks larger than 293122 (at 24 bpp), which we see with the Sharp (and similar) 4k tiled displays.
