    drm/i915: Round tile chunks up for constructing partial VMAs

    When we split a large object up into chunks for GTT faulting (because we
    can't fit the whole object into the aperture) we have to align our cuts
    with the fence registers. Each partial VMA must cover a complete set of
    tile rows or the offset into each partial VMA is not aligned with the
    whole image. Currently we enforce a minimum size on each partial VMA,
    but this minimum size itself was not aligned to the tile row causing
    distortion.
