Current clk unit has multiple header files under pmuif folder.
This has combination of public struct which is accessed outside the
unit and private struct which is accessed within clk unit.
This patch segregates them based on their accessibility.
All private items are moved into ucode_clk_inf.h from pmuif which only
clk can access.
All public items are moved into include/clk.h which other units can
access
This will help in documentation of items for public items.

From gv11b onwards, FECS ucode returns an ACK for set watchdog
timeout method. Failure to wait for this ACK was leading to races,
and in some cases, the ACK could be mistaken for the reply to the
next method.
In particular, this happened for the discover golden image size
method which is sent after set watchdog timeout.
With instrumented FECS ucode, it takes longer for the code to
process the set watchdog timeout method, and the write to ack
that method could happen after nvgpu driver clears the mailbox to
send the discover image size method.
With an invalid golden context image size, FECS ended up causing
an MMU fault while attempting to save past allocated buffer.
Added NVGPU_GR_FALCON_METHOD_SET_WATCHDOG_TIMEOUT to be used with
gops_gr_falcon.ctrl_ctxsw, and implemented 2 variants:
- gm20b_gr_falcon_ctrl_ctxsw, without ACK
- gv11b_gr_falcon_ctrl_ctxsw, with ACK
Added NVGPU_GR_FALCON_SUBMIT_METHOD_F_LOCKED flag to allow
executing above method without re-acquiring FECS lock. Longer term,
the 'flags' could be added to gop_gr_falcon.ctrl_ctxsw parameters.
Use gops_gr_falcon.ctrl_ctxsw instead of register writes to invoke
set watchdog timeout method in gm20b_gr_falcon_wait_ctxsw_ready.
Also replaced calls to gm20b_gr_falcon_ctrl_ctxsw to
gops_gr.falcon.ctrl_ctxsw when appropriate, since there are
multiple variants (gm20b, gp10b and gv11b).
Last, fixed clearing of mailbox 0 in gm20b_gr_falcon_bind_instblk.

To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute on
different hardware resources. This feature proposes modifications
in the software to modify the virtual SM id to TPC mapping across
the mission and redundant contexts. The virtual SM identifier to TPC
mapping is done by nvgpu when setting up the patch context.
The recommendation for the redundant setting is to offset the
assignment by one TPC, and not by one GPC. This will ensure that both
GPC and TPC diversity. The SM and Quadrant diversity will happen
naturally. For kernels with few CTAs, the diversity is guaranteed
to be 100%. In case of completely random CTA allocation,
e.g. large number of CTAs in the waiting queue, the diversity is
1 - 1/#SM, or 87.5% for GV11B, 97.9% for TU104.
Added NvGpu CFLAGS to enable/disable the SM diversity support
"CONFIG_NVGPU_SM_DIVERSITY".
This support is only enabled on gv11b and tu104 QNX non safety build.
