[Mesa-dev] [PATCH v2 20/37] panfrost: Add FBO BOs to batch->bos earlier

[Boris Brezillon]

If we want the batch dependency tracking to work correctly we must
make sure all BOs are added to the batch->bos set early enough. Adding
FBO BOs when generating the fragment job is clearly to late. Add a
panfrost_batch_add_fbo_bos helper and call it in the clear/draw path.
