11b34e891f gpu: nvgpu: Refactor Clk unit.
As a part of refactoring, need to move clk sw/pmu setup functions
from pmu_pstate unit to clk unit as it belongs there.

In this patch the public API is moved from pmu_pstate to clk unit and
named according to private/public API.

65ecd7a181 gpu: nvgpu: Remove fixed wait time for change seq completion
Currently after sending change seq RPC, nvgpu waits for a fixed time
of 20ms.
This CL replaces this with pmu_wait_message_cond, which will return
immediately after getting change seq completion event.
Also added debug fs node to get the change seq execution time.

722fe30d50 gpu: nvgpu: Restructure clk unit
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.

Changes:
1) Separated clk.h which is in /nvgpu/include/pmu

2) Renamed global functions

Intention: At present /nvgpu/include/pmu/clk.h
consists of structures and functions of different
clock units. It is difficult to work on individual
clk units if this file is not separated into
individual units. All stucts and functions in clk.h
are seperated into different clk units.
Individual private clk units were not touched.
Post this patch, the sebsequent patches would make
changes in the individual clk units.
