    drm/i915: Try GGTT mmapping whole object as partial

    If the whole object is already pinned by HW for use as scanout, we will
    fail to move it to the mappable region and so must resort to using a
    partial VMA covering the whole object.

    Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=104513
    Fixes: aa136d9d72c2 ("drm/i915: Convert partial ggtt vma to full ggtt if it
spans the entire object")
