radeon: Add new R600 PCI ids for surface manager

This is the same list of PCI ids added by Alex Deucher in xf86-video-ati commit
aacbd629b02cbee3f9e6a0ee452b4e3f21376bd3.

This is needed since the addition of the surface allocator helper in
commit c51f7f0e ; it needs to differentiate
pre and post-R600 GPUs.
Therefore we should maintain another PCI id list.
