Enable multi-ring ih1 and ih2 for Arcturus only.
For Navi10 family multi-ring has been disabled.
Apparently, having multi-ring enabled in Navi was causing
continus page fault interrupts.
Further investigation is needed to get to the root cause.

drm_dev_alloc() alloc *dev* and set managed.final_kfree to dev to free
itself.
Now from commit 5cdd68498918("drm/amdgpu: Embed drm_device into
amdgpu_device (v3)") we alloc *adev* and ddev is just a member of it.
So drm_dev_release try to free a wrong pointer then.

Also driver's release trys to free adev, but drm_dev_release will
access dev after call drvier's release.

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

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.

Starting in Linux 5.8, the graphics and memory clock frequency were not being
reported for CIK cards. This is a regression, since they were reported correctly
in Linux 5.7.

After investigation, I discovered that the smum_send_msg_to_smc() function,
attempts to call the corresponding get_argument() function of ci_smu_funcs.
However, the get_argument() function is not defined in ci_smu_funcs.

This patch fixes the bug by specifying the correct get_argument() function.
