Clk_mon is used for monitoring of clk and it is an independent unit.
This patch does the following.
*Move the clk_mon struct from clk.h to clk_mon_tu104.h
*create a new clk_mon gpu_ops and assign clk_mon specific ops there.
*Move all the function to clk_mon_tu104.c

8e545ef04b gpu: nvgpu: Fix boardobj allocation size 
In current implementation we are allocating boardobj
in nvgpu_boardobj_construct_super for all units and assigning
that pointer to boardobj type, as the size differe for different
units assigning the boardobj pointer to a common type will
give violations. Fixing them by allocating mem a head
and later call construct_super for elements initialization.

c060e754fc gpu: nvgpu: ELPG dump stats at shutdown 
ELPG_DISALLOW command fails during gk20a shutdown.
It was due to nvgpu_can_busy() which was returning
0 before without acknowledging the ELPG_DISALLOW
command.

Since the system is shutting down so fix this issue
by setting the ACK for disallow command without
waiting for actual ACK from PMU.
In doing so the state machine is also maintained
properly and the driver does not dump fail stats.

In the upstream kernel ACCESS_ONCE is now deprecated with reason as
given in the following related commit:

    commit 381f20fceba8e ("security: use READ_ONCE instead of deprecated
    ACCESS_ONCE")

    ACCESS_ONCE() does not work reliably on non-scalar types. For
    example gcc 4.6 and 4.7 might remove the volatile tag for such
    accesses during the SRA (scalar replacement of aggregates) step.

Replace usages of ACCESS_ONCE with READ_ONCE and WRITE_ONCE in nvgpu.

75eabece8b gpu: nvgpu: Move volt unit from perf to pmu. 
As a part of refactoring volt unit, move volt struct from
perf to pmu.

different units.

b21f300db7 gpu: nvgpu: Refactor Volt unit 
Current volt 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 volt unit.
This patch segregates them based on their accessibility.
All private items are moved into ucode_volt_inf.h from pmuif which only
volt can access.
All public items are moved into include/volt.h which other units can
access
This will help in documentation of items for public items.

e21d70574c gpu: nvgpu: Fix mismatch in Volt boardobj parsing 
There is a mismatch between data parsed by nvgpu struct to pmu struct.
This patch fixes this by correctly parsing the data from vbios and
sending it to pmu.
This was unnoticed till now and started poping up during refactoring.
