freedreno/a3xx: add back a few stalls
Technically we should not need these. CP_LOAD_STATE can be pipelined.
But removing them broke a few piglit tests, like fbo-depth-
GL_DEPTH_COMPONENT24-readpixels. I expect these are just masking a
problem elsewhere, or perhaps they are only needed under some more
specific circumstances. But until that is understood properly, give
back a bit of the perf boost we got from c63450e8.
