Deepak Nibade c33827e122 gpu: nvgpu: add common.gr.obj_ctx unit ...

Add a new unit common.gr.obj_ctx which allocates and initializes GR
context. This unit also takes care of creating global golden image
used to initialize every context.

Add private header obj_ctx_priv.h that defines struct
nvgpu_gr_obj_ctx_golden_image

Add public header obj_ctx.h that exposes functions supported by new unit

This unit now exposes below API to allocate and initialize context
nvgpu_gr_obj_ctx_alloc()

Remove below functions from gk20a/gr_gk20a.c and move them to new unit
with below renames

gr_gk20a_fecs_ctx_bind_channel() -> nvgpu_gr_obj_ctx_bind_channel()
gr_gk20a_fecs_ctx_image_save() -> nvgpu_gr_obj_ctx_image_save()
gk20a_init_sw_bundle() -> nvgpu_gr_obj_ctx_alloc_sw_bundle()
gr_gk20a_alloc_gr_ctx() -> nvgpu_gr_obj_ctx_gr_ctx_alloc()
gr_gk20a_init_golden_ctx_image() ->
		nvgpu_gr_obj_ctx_alloc_golden_ctx_image()

Use new APIs in gk20a_alloc_obj_ctx() to allocate context

For now this unit includes <nvgpu/gr/gr.h> and some h/w headers.
But they will be removed in follow up patches
