radeonsi: emit PA_SC_RASTER_CONFIG

Use per asic golden values.

Programming this register doesn't seem to be strictly
necessary on SI, but programming it wrong leads to
rendering issues or reduced performance so just
go ahead and program the golden values explicitly
to avoid any potential problems down the road.
