drm/ttm: merge ttm_backend and ttm_tt V5
ttm_backend will only exist with a ttm_tt, and ttm_tt will only be of interest when bound to a backend. Merge them to avoid code and data duplication. V2 Rebase on top of memory accounting overhaul V3 Rebase on top of more memory accounting changes V4 Rebase on top of no memory account changes (where/when is my delorean when i need it ?) V5 make sure ttm is unbound before destroying, change commit message on suggestion from Tormod Volden Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>
