    sna: Remove translation from affine HW cursor transformation

    When the CRTC is transformed, we also want to apply that transformation
    to the cursor image so that we can continue to use the HW cursor (but
    have it appear relative to the output and not to the framebuffer).
    However, we need to convert the CRTC transformation relative to the
    cursor and convert it to a simple rotation/scaling/skew transformation
    (we already verify it is an affine) by removing any translation.
