Revert "nvgpu: gp10b: remove EMC floor when GPU Fmin"

This reverts commit c58da17d131bc551f8b3c5a05e60d8375d940f02.

With original patch, we request 0 emc for minimum GPU
frequency, and this causes instability on Quill-B00

Hence revert this patch

Original patch : http://git-master/r/#/c/1284572/
