Moved nvgpu_clk_pmupstate structure from gk20a to
nvgpu_pmu.The aim is to have single pmu structure inside
gk20a, that is "nvgpu_pmu" struct and all the global
structures of all units in PMU should be included in
"nvgpu_pmu" struct.

Currently, both clk_arb and channels use their own implementation of
a background worker. These implementations are almost identical and can
be extracted out into a single self-contained unit name nvgpu_worker.
Another advantage of using a single worker unit is to avoid duplication
of Unit Tests for this unit in other units.
channel and clk_arb units provide their own specific implementations
via an ops interface named nvgpu_worker_ops which is a part of the
nvgpu_worker struct.
The following high level APIs are exposed by the nvgpu_worker
nvgpu_worker_should_stop
nvgpu_worker_enqueue
nvgpu_worker_init
nvgpu_worker_deinit
The nvgpu_worker_ops containg the following function pointers
pre_process
wakeup_early_exit
wakeup_post_process
wakeup_process_item
wakeup_condition
wakeup_timeout
The specific code in channel and clk_arb is changed to use the above
implementations instead of their own separate implementations.

Description:
Present p-state unit handle both pstate boardobj and
initializing all the units. As part of restructuring,
the pstate unit is separated into two units:
1) Perf_pstate: This unit will handle pstate boardobjs.
2) Pmu_pstate: This unit will initialize all the units
which supoort performance states.
Changes:
1) Created pmu_pstate unit.
2) Pstate boardobjs are moved under perf_pstate which
is under perf unit.

This patch fixes below two issues.
1.Currently clk arb exit is called after GPU registers are released.
This causes crash when clk arb WQ accesses GPU HW register for status.
The ideal way is to exit the clk_arb which removes the WQ from running
before calling lockout register.
2.Check if dGPU is dying during processing of PMU Commands.
This prevents race condition when PMU is waiting for response and device
is shutdown.

Description:
nvgpu_clk_pmupstate is the global structure in clk units. It is declared
in clk.h and all clk units will include clk.h header.
nvgpu_clk_pmupstate struct will have structure pointers to all clk units
and will include genereic function pointers which are used by most clk
units. The reason why the function pointers is defined in this sturct,
and not included inside g->ops is because, these are only clk specific
functions and rest of the driver code is not dependent on this.
Each unit will have init function to allocate memory for its structure
and will initialize its local functions.
Changes:
1) Introduced nvgpu_clk_pmupstate in clk.h file. All the changes needed
to call the above struct from individual clk units.
2) Removed cyclic dependency headers in clk units by calling function
through pointers defined in clk.h.
3) Initialization of each unit is done in respective unit instead of
doing it in clk unit. Added *_init_pmupstate and *_free_pmupstate to
individual clk units.
4) Each unit clean up will be done separately while refactoring that
unit.

MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch ensures that WARN and WARN_ON always return void; and
introduces a new nvgpu_do_assert construct to trigger the equivalent
of WARN_ON(true) so that stack can be dumped (depends on OS support)
