For amdgpu_get_pp_force_state, amdgpu_get_pp_cur_state already takes
care of device state check. In other cases, values are returned from
driver cached variables and are not dependent on device state.

If a device supports runtime pm, then pm_runtime_get_if_active returns 0
if a device is not active and 1 if already active. However, if a device
doesn't support runtime pm, the API returns -EINVAL. A device not
supporting runtime pm implies it's not affected by runtime pm and it's
active. Hence no need to get() to increment usage count. Remove < 0
return value check. Also, ignore runpm state to determine active status.
If the device is already in suspend state, disallow access.

Wrap the checks before device access in helper functions and use them
for device access. The generic order of APIs now is to do input argument
validation first and check if device access is allowed.

smu->workload_mask is IP specific and should not be messed with in
the common code. The mask bits vary across SMU versions.
Move all handling of smu->workload_mask in to the backends and
simplify the code. Store the user's preference in smu->power_profile_mode
which will be reflected in sysfs. For internal driver profile
switches for KFD or VCN, just update the workload mask so that the
user's preference is retained. Remove all of the extra now unused
workload related elements in the smu structure.
v2: use refcounts for workload profiles
v3: rework based on feedback from Lijo
v4: fix the refcount on failure, drop backend mask
v5: rework custom handling
v6: handle failure cleanup with custom profile
v7: Update documentation

Together with the feature to enable or disable zero RPM in the last
commit, it also makes sense to expose the OD setting determining under

Don't wake up the GPU for reading pm values. Instead, take a runtime
powermanagement ref when trying to read it if and only if the GPU is
already awake.
This avoids spurious wake ups (eg: from applets).
We use pm_runtime_get_if_in_active because we care about "is the GPU awake?"
not about "is the GPU awake and something else prevents suspend?".

Reading pm values from the GPU shouldn't prevent it to be suspended
by resetting the last active timestamp (eg: if an background app
monitors GPU sensors every second, it would prevent the autosuspend
sequence to trigger).

Add support to set/get information about different DPM policies. The
support is only available on SOCs which use swsmu architecture.
A DPM policy type may be defined with different levels. For example, a
policy may be defined to select Pstate preference and then later a
pstate preference may be chosen.
