2024-11-20drm/amdgpu: Add init level for post reset reinitLijo Lazar1-0/+2
When device needs to be reset before initialization, it's not required for all IPs to be initialized before a reset. In such cases, it needs to identify whether the IP/feature is initialized for the first time or whether it's reinitialized after a reset. Add RESET_RECOVERY init level to identify post reset reinitialization phase. This only provides a device level identification, IP/features may choose to track their state independently also.
