[PATCH] drm/amd/amdgpu: use advanced TDR mode by default

[Bokun Zhang]

From: Bokun Zhang <bokun.zhang at amd.com>

In the patch about advanced TDR mode, we force to always set
amdgpu_gpu_recovery=2 under SRIOV. This is not ideal, since we
may want to revert back to use the legacy TDR routine.

Therefore, we only set amdgpu_gpu_recovery=2 when it is
configured as AUTO, which is the default value (gpu_recovery=-1)
