[How]
We unfortunately can't drop this function in its entirety from
prepare_planes since we don't know the afb->address at commit_check
time yet.
So instead of querying new tiling_flags and tmz_surface use the ones
from the plane_state directly.
While we're at it, also update the force_disable_dcc option based
on the state from atomic check.
