    drm/i915: Use unchecked uncore writes to flush the GTT

    As the GTT is outside of the powerwell, we can simplify flushing the
    GGTT writes by using an unchecked mmio write and post.

    v2: s/unc/uncore/

    drm/i915: Use unchecked writes for setting up the fences

    As the fence registers are not part of the engine powerwells, we do not
    need to fiddle with forcewake in order to update a fence. Avoid using
    the heavyweight debug checking normal mmio writes as the checking
    dominates the selftest runtime and is superfluous!

    In the process, retire the I915_WRITE() implicit macro with the new
    intel_uncore_write interface.

    v2: s/unc/uncore/
