drm/amdgpu: Fix a redundant kfree

To fix it, remove driver's release and set managed.final_kfree to adev.

drm/amdgpu: Fix bug in reporting voltage for CIK

On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.

This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.

However, the get_argument() function is not defined in ci_smu_funcs.

drm/amd/pm: avoid false alarm due to confusing softwareshutdowntemp setting

Normally softwareshutdowntemp should be greater than Thotspotlimit.
However, on some VEGA10 ASIC, the softwareshutdowntemp is 91C while
Thotspotlimit is 105C. This seems not right and may trigger some

drm/amd/powerplay: Fix hardmins not being sent to SMU for RV

[Why]
DC uses these to raise the voltage as needed for higher dispclk/dppclk
and to ensure that we have enough bandwidth to drive the displays.

There's a bug preventing these from actuially sending messages since
it's checking the actual clock (which is 0) instead of the incoming
clock (which shouldn't be 0) when deciding to send the hardmin.

drm/amd/display: Reject overlay plane configurations in multi-display scenarios

[Why]
These aren't stable on some platform configurations when driving
multiple displays, especially on higher resolution.

In particular the delay in asserting p-state and validating from
x86 outweights any power or performance benefit from the hardware
composition.

Under some configurations this will manifest itself as extreme stutter
or unresponsiveness especially when combined with cursor movement.

[How]
Disable these for now. Exposing overlays to userspace doesn't guarantee
that they'll be able to use them in any and all configurations and it's
part of the DRM contract to have userspace gracefully handle validation
failures when they occur.

Valdiation occurs as part of DC and this in particular affects RV, so
disable this in dcn10_global_validation.

drm/amd/display: use correct scale for actual_brightness

Documentation for sysfs backlight level interface requires that
values in both 'brightness' and 'actual_brightness' files are
interpreted to be in range from 0 to the value given in the
'max_brightness' file.

With amdgpu, max_brightness gives 255, and values written by the user
into 'brightness' are internally rescaled to a wider range. However,
reading from 'actual_brightness' gives the raw register value without
inverse rescaling. This causes issues for various userspace tools such
as PowerTop and systemd that expect the value to be in the correct
range.

Introduce a helper to retrieve internal backlight range. Use it to
reimplement 'convert_brightness' as 'convert_brightness_from_user' and
introduce 'convert_brightness_to_user'.
