In different traces for different GPU models I see the same pattern:
0x00c80000, /* [00A00] PA.VIEWPORT_SCALE_X = 200.000000 */
0xff880000, /* [00A04] PA.VIEWPORT_SCALE_Y = -120.000000 */
etna_f32_to_fixp16(..) handles the negative case differently then blob. In the
concrete example -120 gets converted to 0xff880001. Switch to S_FIXED(..) to
simplify our code and to get the same results as blob.
