The ttm_plac structure allows page-based allocation,
to support byte-based allocation using default or custom
ttm_resource_manager_func function like
ttm_range_man_alloc, amdgpu_gtt_mgr_new,
i915_ttm_buddy_man_alloc,nouveau_vram_manager_new etc.
Change the ttm_place structure member fpfn, lpfn, mem_type to
res_start, res_end, res_type.
Change the unsigned to u64.
Fix the dependence in all the DRM drivers and
clean up PAGE_SHIFT operation.
v1 -> v2: fix the bug reviewed by Michel, addressing Stanislaw
missing justification.
