freedreno/drm: specify presumed buffer address in drm_msm_gem_submit_bo

Zan Dobersek requested to merge zdobersek/mesa-fork:fd_submit_bo_presumed into main 
freedreno/drm: specify presumed buffer address in drm_msm_gem_submit_bo

Some kernels use the 'presumed' field in the drm_msm_gem_submit_bo struct
as the definitive buffer object address basis. When not set, any command
stream ends up in a GPU hang due to incorrect iova calculation in the
kernel.
