Fix GPU reset on DCN 3.1.4

[Public]

Hi,

Rajib recently found that GPU reset is failing on DCN 3.1.4 with 6.1.y. It's because of some missing commits in 6.1.y that skip the appropriate functions to match the GPU's graphics architecture. Backporting these and GPU reset works again. Can you please bring these back to 6.1.y and 6.2.y?

Thanks,
