drm/i915/fbdev: Stop repeating tile configuration on stagnation

Browse source

If we cease making progress in finding matching outputs for a tiled
configuration, stop looping over the remaining unconfigured outputs.

v2: Use conn_seq (instead of pass) to only apply tile configuration on
first pass.

Fixes: b0ee9e7fa5 ("drm/fb: add support for tiled monitor configurations. (v2)")
