Chris Wilson a38baaade4 drm/i915: Replace WARN inside I915_READ64_2x32 with retry loop
commit ee0a227b7a upstream.

Since we may conceivably encounter situations where the upper part of the
64bit register changes between reads, for example when a timestamp
counter overflows, change the WARN into a retry loop.
