softpipe: Enable PIPE_CAP_MIXED_COLORBUFFER_FORMATS

  
It seems softpipe actually supports this. This change enables the
following piglits as passing without regressions in the gpu test set:

 gl-3.1-mixed-int-float-fbo
 gl-3.1-mixed-int-float-fbo int_second
 fbo-blending-format-quirks

Changes for deqp:
