[PATCH] etnaviv: Set up GC3000 states, fix point sprite rendering

[Wladimir J. van der Laan]

Set up new states that the blob started setting for GC3000 consistently.

This makes sure that when another test or driver leaves the GPU in
unpredictable state, these states are set up correctly for our
rendering.

Also, setting PA_VIEWPORT_UNK00A84 to fui(8192.0) is necessary
to make point sprite rendering on GC3000 work.
