Following changes are made in this patch. 1) Change unnamed structs within gpu_ops to named structs with the prefix gops_*. 2) Each named struct gops_ are moved into a separate gops specific file under include/nvgpu/gops/ 3) struct gpu_ops is moved into a separate file include/nvgpu/gpu_ops.h and all other dependent struct gops_* are included in this header. 4) Direct references to include/nvgpu/gops are removed from files as its enough to include gk20a.h.
