drm/amdkfd: Handle VM faults in KFD

Browse source

1. Pre-GFX9 the amdgpu ISR saves the vm-fault status and address per
   per-vmid. amdkfd needs to get the information from amdgpu through the
   new get_vm_fault_info interface. On GFX9 and later, all the required
   information is in the IH ring
2. amdkfd unmaps all queues from the faulting process and create new
   run-list without the guilty process
3. amdkfd notifies the runtime of the vm fault trap via EVENT_TYPE_MEMORY
