GPUs with Empty pstate table

[Ricks-Lab]

In trying an older R9 290X card, I found that the driver file which should contain p-state details is empty. Perhaps this format of pp_od_clk_voltage should be classified as "type 0".

Anyone else seeing behavior in any compatible GPUs that is inconsistent with the assumed behavior of the tools? For this case, I have already added a type 0 and cards with this behavior should be classified appropriately. Thanks!

I have implemented Type 0 GPU and have correct behavior for this across all tools. Let me know if any sees other related issues.
