Currently clk_arb needs PSTATE to be true for dGPU.
Setting PSTATE only FALSE, causes issue as clk_arb fails.
There is no such dependency of PSTATE on iGPU.
Making it unified with a call to check_clk_arb_support().
This call is implemented based on its dependency in iGPU, dGPU.
check_clk_arb_support returns true if supported, else false.

Currently there are multiple BOARDOBJGRP SET/GET_STATUS construct
added to support for 3.5 pstate, _pack boardobjs & to fetch respective
offset/size of boardobjs from PMU super surface.
With super surface member descriptor(SSMD) support, boardobj offset
will be part of SSMD lookup table which is part of PMU super surface
buffer & updated by PMU RTOS during init stage,
So, making changes to use common BOARDOBJGRP SET/GET_STATUS
construct define which fetchs offset/size from SSMD,
& deleting other BOARDOBJGRP construct defines.

Currently clk_arb wq waits only for tasks.
Sometimes this doesnt invoke wq when thread_stop is called.
Add a check for thread_stop when waiting in wq.
Remove atomic_inc when no job is submitted.
Use current_time_ns() instead of ptimer to get time.

In the below scenario
1. nvrm app requests & gets all VF points from nvgpu.
2. nvrm stores all the VF points and starts setting each point.
3. During step 2, VF gets updated in nvgpu due to some events.
4. There is a mismatch b/w points in nvrm and VF table in nvgpu.
5. If nvrm freq is less than nvgpu freq , PMU cant program.
Makesure highest between nvrm and VF table goes to PMU

All slave clock should be quantized as per step size.
TU104 has 15Mhz as step size.
Enable clk_arb without enabling clk_freq_controller.
clk_freq_controller is not needed for Auto use case.
Increase the maxclk only when master is less that slave clock.
This is needed when gpcclk is less than slave P0 min.
Use get_status to get Vim and use it for change sequencer.
Add support for Device Events

The container_of() macro used in nvgpu produces the following
set of MISRA required rule violations:
* Rule 11.3 : A cast shall not be performed between a pointer to
object type and a pointer to a different object type.
* Rule 11.8 : A cast shall not remove any const or volatile
qualification from the type pointed to be a pointer.
* Rule 20.7 : Expressions resulting from the expansion of macro
parameters shall be enclosed in parentheses.
Using the same modified implementation of container_of() as that
used in the nvgpu_list_node/nvgpu_rbtree_node routines eliminates
the Rule 11.8 and Rule 20.7 violations and exchanges the Rule 11.3
violation with an advisory Rule 11.4 violation.
This patch uses that same equivalent implementation in two new
(static) functions that are used to replace references to
container_of() references in clk arb code:
* nvgpu_clk_dev_from_refcount
* nvgpu_clk_session_from_refcount
It should be noted that replacement functions still contain
potentially dangerous (and non-MISRA compliant code) and that it is
expected that deviation requests will be filed for the new advisory
rule violations accordingly.
