Debarshi Dutta 38ce6fa717 gpu: nvgpu: change unnamed structs to named structs
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.
