drm/amd/pm: Fix get_if_active usage

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.

drm/amd/pm: fix and simplify workload handling

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

Whilst we have support for setting fan curves there is no support for

present in the OverDriveTable, hook them up to a sysctl setting so users
can influence this behaviour.

drm/amd/pm: use pm_runtime_get_if_active for debugfs getters

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?".
