Rename gr_reset_mutex to engines_reset_mutex and acquire it
before initiating recovery. Recovery running in parallel with
engine reset is not recommended.
On hitting engine reset, h/w drops the ctxsw_status to INVALID in
fifo_engine_status register. Also while the engine is held in reset
h/w passes busy/idle straight through. fifo_engine_status registers
are correct in that there is no context switch outstanding
as the CTXSW is aborted when reset is asserted.
Use deferred_reset_mutex to protect deferred_reset_pending variable
If deferred_reset_pending is true then acquire engines_reset_mutex
and call gk20a_fifo_deferred_reset.
gk20a_fifo_deferred_reset would also check the value of

A comment for gk20a_fifo_update_runlist() says:
/* add/remove a channel from runlist
special cases below: runlist->active_channels will NOT be changed.
(ch == NULL && !add) means remove all active channels from runlist.
(ch == NULL && add) means restore all active channels on runlist. */
Those special cases call for a new function, so add that. Delete the
update_runlist HAL op and add update_for_channel (like update_runlist
without the special cases) and reload (no channel to add or remove, just
the special cases).
While at it, rename gk20a_fifo_update_runlist_ids to
nvgpu_runlist_reload_ids. It's common across chips and does what the
reload HAL does but for a list of several IDs.

Add new unit common/gr/subctx.c to manage GR subcontext
This unit provides interfaces to allocate/free/load GR subcontext
Add new header file include/nvgpu/gr/subctx.h to declare all the
interfaces.
Right now channel_gk20a structure directly includes a nvgpu_mem
for context header.
Declare a new structure nvgpu_gr_subctx for subcontext and include
this from channel_gk20a
Make all necessary changes to refer ctx_header from subctx instead
of directly referencing it from channel

When an engine faults due to unbound instance block, all
active TSGs are currently aborted. This includes the TSG
used by vidmem-clear task to clear vidmem buffers. From
this point nvgpu_vidmem_clear cannot submit jobs anymore.
Define TSG in MM CE context as non-abortable, and skip it
when aborting active TSGs.
