This patch causes piglit regressions on i.MX6QP. For example the
fbo-blend-color test is going from some broken subtests to a complete
failure. I'm not sure if it's a failure on the on the test or Mesa side,
the etnaviv pipe driver seems to handle things correctly.
Given how close we are to the 17.2 branchpoint we need either a
volunteer to look into this (I don't have the time currently) or we
should revert this patch and try again after 17.2.

Lucas
