c90fcbae2a gpu: nvgpu: fix MISRA Rule 2.2 no dead code
MISRA rule 2.2 defines dead code as "operations which are executed but
removal of these operations has no effect on program behavior".
Variable initializations violate this rule if initialized value is not
used and replaced.

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.
