drm/amdgpu: always allocate cleared VRAM for GEM allocations
This adds allocation latency, but aligns better with user
expectations. The latency should improve with the drm buddy
clearing patches that Arun has been working on.
In addition this fixes the high CPU spikes seen when doing
wipe on release.
v2: always set AMDGPU_GEM_CREATE_VRAM_CLEARED (Christian)
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3528
Fixes: a68c7eaa7a8f ("drm/amdgpu: Enable clear page functionality")
