i830: Fix collision between I830_UPLOAD_RASTER_RULES and I830_UPLOAD_TEX(0)
I830_UPLOAD_RASTER_RULES and I830_UPLOAD_TEX(0) are trying to occupy
the same bit. Move the texture bits upwards a bit to make room for
I830_UPLOAD_RASTER_RULES.
Now the driver will actually upload the raster rules which is rather
important to get the provoking vertex right. Fixes the appearance
of glxgears teeth on gen2.
