drm/i915/dsb: Compute use_dsb earlier

Browse source

Skip all the commit completion interrupt stuff on the
chained DSB when we don't take the full DSB path (ie. when
the plane/pipe programming is done via MMIO). The commit
completion will be done via the CPU side vblank interrupt.

Currently this is just a redundant interrupt, so not a big
deal. But in the future we'll be moving the TRANS_PUSH write
into the chained DSB as well, and that we definitely don't
want to do when it's also being done by the CPU from
intel_pipe_update_end().
