Add support in nvgpu to parse and get the freq cap from DT.
The patch does below
Parse the DT and gets the freq cap value during probe.
During clk_arb init compare this with P0.Max and takes the lowest.
Send change_seq with the new value and set dgpu freq.
Use the lowest for "get points","get default","set VF".

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.

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.
