drm/i915/mst: update slot information for 128b/132b
128b/132b supports using 64 slots starting from 0, while 8b/10b reserves
slot 0 for metadata.
Commit d6c6a76f80a1 ("drm: Update MST First Link Slot Information Based
on Encoding Format") added support for updating the topology state
accordingly, and commit 41724ea273cd ("drm/amd/display: Add DP 2.0 MST
DM Support") started using it in the amd driver.
This feels more than a little cumbersome, especially updating the
information in atomic check. For i915, add the update to MST connector
.compute_config hook rather than iterating over all MST managers and
connectors in global mode config .atomic_check. Fingers crossed.
v3:
- Propagate errors from intel_dp_mst_update_slots() (Ville)
v2:
- Update in .compute_config() not .atomic_check (Ville)
