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;

Add esr_bpt_pending_events hal to report the type of
esr_bpt_pending_events to isr to process.
Add hal functions in gr instead of moving to gr.intr unit, as it
is part of non safety code.

gfxp_wfi_timeout_count/unit fields were stored in gr_gk20a.ctx_vars
struct so that any user could configure them through sysfs nodes
But the sysfs nodes are legacy and not being actively used by anyone.
Hence delete the sysfs nodes to configure these fields.
Since the gfxp timeout unit/count can now be statically programmed,
make following changes
- remove g->ops.gr.init_gfxp_wfi_timeout_count() hal
- remove g->ops.gr.get_max_gfxp_wfi_timeout_count() hal
- update g->ops.gr.init.preemption_state() hals to configure the values
using macros instead of caller passing the values
- update g->ops.gr.init.gfxp_wfi_timeout() hals to configure the values
using macros instead of caller passing the values
Finally, we don't need to store gfxp_wfi_timeout_count/unit fields
anymore, hence delete them from gr_gk20a.ctx_vars
