We use below APIs to update patch context
gr_gk20a_ctx_patch_write_begin()
gr_gk20a_ctx_patch_write_end()
gr_gk20a_ctx_patch_write()
Since patch context is owned by gr/ctx unit, move these APIs
to this unit and rename them to

We currently load and create new graphics context image in
gr_gk20a_load_golden_ctx_image()
This API will first load local golden image in new context
image and then initialize context appropriately by calling
g->ops.gr.ctxsw_prog() HALs
Move this sequence to gr/ctx unit and rename the API as
nvgpu_gr_ctx_load_golden_ctx_image()
Note that call to g->ops.gr.update_ctxsw_preemption_mode()
is moved out of this API and called directly from
gk20a_alloc_obj_ctx()

Currently all the global contex buffers are mapped into each graphics
context. Move all the mapping/unmapping support to gr/ctx unit since
all the mappings are owned by context itself
Add nvgpu_gr_ctx_map_global_ctx_buffers() that maps all the global
context buffers into given gr_ctx
Add nvgpu_gr_ctx_get_global_ctx_va() that returns VA of the mapping
for requested index
Remove g->ops.gr.map_global_ctx_buffers() since it is no longer
required. Also remove below APIs
gr_gk20a_map_global_ctx_buffers()
gr_gk20a_unmap_global_ctx_buffers()
gr_tu104_map_global_ctx_buffers()
Remove global_ctx_buffer_size from nvgpu_gr_ctx since it is no

Add new unit common/gr/ctx.c to manage GR context
This unit provides interfaces to allocate/free/map/unmap GR context,
patch context, pm context, ctxsw {preempt/spill/betacb/pagepool/rtvcb}
buffers.
It also provides APIs to set size of above buffers
Add new header file include/nvgpu/gr/ctx.h to declare all the interfaces.
Move nvgpu_gr_ctx, patch_desc, pm_ctx_desc, zcull_ctx_desc structures
to this unit
Add new structure nvgpu_gr_ctx_desc to hold context description
parameters. For now we add sizes of all the buffers here.
Add this structure to gr_gk20a for global reference
Remove gr_gp10b_alloc_buffer() since it is no longer used
Rename g->ops.gr.alloc_gfxp_rtv_cb() to g->ops.gr.init_gfxp_rtv_cb()
since this HAL now only sets the size of rtvcb ctxsw buffer
Remove gr->ctx_vars.buffer_size and gr->ctx_vars.buffer_total_size
since they were redundant. We already have gr->ctx_vars.golden_image_size
to denote golden image size

Current code creats golden image using dedicated gr_ctx called
GOLDEN_CTX. But on RM server it's no easy to create a GOLDEN_CTX since
virtual addresses are managed by guest OSes. There's no special reason
why we have to use a separate gr_ctx for golden image. This patch moves
it to use current channel gr_ctx. And the function will be re-useable
by RM server.

Add new unit common/gr/global_ctx.c to manage GR global context buffers
This unit provides interfaces to allocate/free/map/unmap all the global
context buffers. It also provides APIs to get/set size of the buffers,
and to get memory handle of the buffers
Use interfaces exposed by this unit instead of directly accessing global
context buffers in common code
Add new header file include/nvgpu/gr/global_ctx.h to declare all the
interfaces.
Rename "struct gr_ctx_buffer_desc" to "struct nvgpu_gr_global_ctx_buffer_desc"
which holds all data for each global context
Remove void *priv since it is no longer used
Add size to the desc structure to store the requested size
Remove global_ctx_buffer_size from struct nvgpu_gr_ctx since it is no longer
