drm/radeon/kms: adjust evergreen display watermark setup
This patch fixes two issues:
- A disabled crtc does not use any lb, so return 0 for
lb size. This makes the display priority calculation
more exact.
- Only use 1/2 and whole lb partitions. Using smaller
partitions can cause underflow to one of the displays
if you have multiple large displays on the same lb.
