Lijo Lazar a86e0c0e94 drm/amdgpu: Add init level for post reset reinit
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.

Sunil Khatri 502d76308d drm/amdgpu: validate resume before function call
Before making a function call to resume, validate
the function pointer like we do in sw_init.

Use the helper function amdgpu_ip_block_resume where
same checks and calls are repeated.

Lijo Lazar f8a499aed2 drm/amdgpu: Keep reset handlers shared
Instead of maintaining a list per device, keep the reset handlers common
per ASIC family. A pointer to the list of handlers is maintained in
reset control.
