gpu: nvgpu: avoid gr_falcon dependency outside gr

Browse Source 
Basic units like fifo, rc are having dependency on
gr_falcon. Avoided outside gr units dependency on gr_falcon
by moving following functions to gr:

int nvgpu_gr_falcon_disable_ctxsw(struct gk20a *g,
			struct nvgpu_gr_falcon *falcon); ->
int nvgpu_gr_disable_ctxsw(struct gk20a *g);

int nvgpu_gr_falcon_enable_ctxsw(struct gk20a *g,
			struct nvgpu_gr_falcon *falcon); ->
int nvgpu_gr_enable_ctxsw(struct gk20a *g);
int nvgpu_gr_falcon_halt_pipe(struct gk20a *g); ->
		int nvgpu_gr_halt_pipe(struct gk20a *g);

HALs also moved accordingly and updated code to reflect this.

Also moved following data back to gr from gr_falcon:
struct nvgpu_mutex ctxsw_disable_mutex;
int ctxsw_disable_count;
