From: Jerome Glisse <jgli...@redhat.com>
The ucode we got for hawaii does not support 0xffff1000 special nop
packet type 3 and this leads to gpu reading invalid memory. As packet
type 2 still exist just use packet type 2.
Note this only partialy fix hawaii issues and some zbuffer tiling
issues are still present.
Changed since v1:
- use packet type 2 instead of packet 3.
