2018-05-14drm/i915/execlists: Relax CSB force-mmio for VT-dChris Wilson
The original switch to use CSB from the HWSP was plagued by the effect of read ordering on VT-d; we would read the WRITE pointer from the HWSP before it had completed writing the CSB contents. The mystery comes down to the lack of rmb() for correct ordering with respect to the writes from HW, and with that resolved we can remove the VT-d special casing.
