drm/ttm: isolate dma data from ttm_tt V4
Move dma data to a superset ttm_dma_tt structure which herit from ttm_tt. This allow driver that don't use dma functionalities to not have to waste memory for it. V2 Rebase on top of no memory account changes (where/when is my delorean when i need it ?) V3 Make sure page list is initialized empty V4 typo/syntax fixes Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>
