[PATCH 3/5] drm/ttm: Use only DRM_MM_SEARCH_BELOW for TTM_PL_FLAG_TOPDOWN

[Michel Dänzer]

From: Michel Dänzer <michel.daen...@amd.com>

DRM_MM_SEARCH_BEST gets the smallest hole which can fit the BO. That seems
against the idea of TTM_PL_FLAG_TOPDOWN:

* The smallest hole may be in the overall bottom of the area
* If the hole isn't much larger than the BO, it doesn't make much
  difference whether the BO is placed at the bottom or at the top of the
  hole
