etnaviv: emit PS start and end PC states only on shader changes

Browse source 
There is no reason to emit those states on framebuffer changes. While the
framebuffer format change might change the fragment shader due to R/B
swapping in the shader, this triggers compilation of a new shader variant
which will dirty the shader state as needed.
