drm/amd/display: Prevent bandwidth overflow
[Why]
At very high pixel clock, bandwidth calculation exceeds 32 bit size
and overflow value. This causes the resulting selection of link rate
to be inaccurate.
[How]
Change order of operation and use fixed point to deal with integer
accuracy. Also address bug found when forcing link rate.
