Patrick Lerda 88ae449dbc r600: fix rv770 dot4 operations
Using a PV register which is not PV.x, after a dot4 operation,
does not work on rv770. Anyway, this does work on evergreen
but this is not documented.

This change updates this behavior for all the r600 gpus
which fixes the issue on rv770. It adds max4 which has the
same requirement in the case of max4 being implemented.

Here are some of the affected tests on rv770:
piglit/bin/fp-abs-01 -auto -fbo
glcts --deqp-case=KHR-GL31.buffer_objects.triangles
piglit/bin/shader_runner generated_tests/spec/glsl-1.10/execution/built-in-functions/fs-distance-vec2-vec2.shader_test -auto -fbo

Fixes: 942e6af40b ("r600/sfn: use PS and PV inline registers when possible")
