drm/amdgpu: Delete GMC 8 soft reset

Browse source

We should only reset the memory controller during ASIC reset
and only when it's absolutely necessary. Otherwise, resetting
the memory controller typically just breaks everything and
on dGPUs may also clear the contents of VRAM (it's unclear if
it really does, but it's likely).

Specifically for GMC 8, the memory controller is reset as part
of the ASIC reset and otherwise should be left alone.
