gpu: nvgpu: remove golden_image_initialized flag from gr_gk20a struct

Browse Source 
struct gr_gk20a defines boolean flag golden_image_initialized to
indicate if golden_image is initialized or not
common.gr.obj_ctx also added a flag of its own to check if golden_image
is ready

Add new API nvgpu_gr_obj_ctx_is_golden_image_ready() in
common.gr.obj_ctx unit to get status of golden_image

Use this new API everywhere to check if golden image is ready
Remove g->gr.ctx_vars.golden_image_initialized

Also remove ctx_mutex from struct gr_gk20a

Add new flag golden_image_initialized to struct nvgpu_pmu_pg and set it
when golden image is initialized. This is needed to avoid circular
dependency between GR and PMU
