Instead of using multiple struct use a single nvgpu_clk_slave_freq
to store the slave freq of gpcclk.
With this patch single struct can be used by both clk_arb and clk_domain.
This will remove nvgpu_set_fll_clk struct as nvgpu_clk_slave_freq serves
the purpose.

As a part of refactoring move nvgpu_clk_domain struct from public
to private.
This will help to have arch consistency across all units.
Use public functions to fetch the data across other units.
The following functions are added to access data in clk_domain unit.
*nvgpu_pmu_clk_domain_get_f_points()--> To get freq points
*nvgpu_pmu_clk_domain_update_clk_info() --> To update change seq script
with clock domain data

Nvgpu uses RPC to get target voltage for a freq, though this gets
the latest Voltage, there could be mismatch b/w data in nvgpu & PMU.
To make it consistent, use the local VF table for getting the voltage.
Also the slave ratio calculation is inaccurate due to quantization.
So instead of calculating, use the slave ratio from parsed vbios table.

Some functions are not accessing hardware directly
but are being called using HAL ops: For example
.init = gv100_bios_init,
.preos_wait_for_halt = gv100_bios_preos_wait_for_halt,
.preos_reload_check = gv100_bios_preos_reload_check,
.devinit = gp106_bios_devinit,
.preos = gp106_bios_preos,
.verify_devinit = NULL,
This was being called as:
g->ops.bios.init(g)
g->ops.bios.preos_wait_for_halt(g)
g->ops.bios.preos_reload_check(g)
g->ops.bios.preos(g)
g->ops.bios.devinit(g)
g->ops.bios.verify_devinit(g)
Change the function access by using sw ops, like:
Create new function: nvgpu_bios_sw_init()
and based on hardware chip call the chip specific
bios sw init function: nvgpu_gv100_bios_sw_init()
and nvgpu_tu104_bios_sw_init()to assign the sw
ops

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.
