gpu: nvgpu: add HALs to allocate/map/commit global context buffers

Add below new HALs to allocate/map/commit global context buffers
gops.gr.alloc_global_ctx_buffers()
gops.gr.map_global_ctx_buffers()
gops.gr.commit_global_ctx_buffers()

Set these HALs for all the supported GPUs

We right now re-use below APIs to set these HALs
gr_gk20a_alloc_global_ctx_buffers()
gr_gk20a_map_global_ctx_buffers()
gr_gk20a_commit_global_ctx_buffers()
