[Mesa-dev] [PATCH 2/2] radeonsi: fix viewport clipping magic.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This fixes the CTS ARB_viewport_array tests and the
arb_viewport_array-render-viewport-2 test I sent to the piglit list.

I'm not sure what this register does, or if we should ever not
be setting it, but lets just set it always for now.
