85cfe09655 drm/amdgpu/cz: unforce dpm levels before forcing to low/high
This is necessary to properly reset the min/max limits before
clamping them otherwise we may get improper clamping depending
on what what was the last forced level.

05188312e2 drm/amdgpu/cz: don't call smu_init on resume
smu_init allocates buffers and initializes them.  It does not
touch the hw.  There is no need to do it again on resume.  It
should really be part of sw_init (and smu_fini should be part
of sw_fini), but we need the firmware sizes from the other IPs
for firmware loading so we have to wait until sw init is done
for all other IPs.

5fc3aeeb9e drm/amdgpu: rename amdgpu_ip_funcs to amd_ip_funcs (v2)
The structure is renamed and moved to amd_shared.h to make
the component independent.  This makes it easier to add
new components in the future.

Enable UVD dpm (dynamic power management) and powergating.  UVD dpm dynamically scales the UVD
