drm/ttm: Add new callbacks to ttm res mgr
We are adding two new callbacks to ttm resource manager
function to handle intersection and compatibility of
placement and resources.
v2: move the amdgpu and ttm_range_manager changes to
separate patches (Christian)
v3: rename "intersect" to "intersects" (Matthew)
v4: move !place check to the !res if and return false
in ttm_resource_compatible() function (Christian)
v5: move bits of code from patch number 6 to avoid
temporary driver breakup (Christian)
