This reduces the latency of pinning framebuffers by re-using the previous mapping, if available. Additionally, DPT is preallocated when creating the FB, instead of performing a bo allocation on every pin. Remove the safety check in the first patch again, I didn't realize it was needed even without the initial FB GGTT pinning removal.
