Subject: [PATCH] drm/amdgpu/SRIOV: Only reset hw.status for target IP
From: Jiange Zhao <jiange.z...@amd.com>
In the old way, when doing IH hw_init, PSP, nv_common
and GMC hw.status would be reset to false, even though
their hw_init have been done. In the next step, fw_loading,
PSP would do hw_init again.
In the new way, only reset hw.status to false for the target
IP in the list. In this way, PSP will only do hw_init once.
