drm/amdgpu: Delete GMC v6-v7 soft_reset() code

Browse source

Note that the soft reset code for GMC v6-v7 was never
called from anywhere, so there is no loss of functionality
from this commit. The implementation looks plausible but
it was never enabled or tested, and unlikely to be useful.

We should only reset the memory controller during ASIC reset
and otherwise leave it alone. Resetting the memory controller
can break everything and risks losing the contents of VRAM
(it's unclear if VRAM is lost or not, but it's likely).
