drm/amdkfd: add svm_bo reference for eviction fence
[why] As part of the SVM functionality, the eviction mechanism used for SVM_BOs is different. This mechanism uses one eviction fence per prange, instead of one fence per kfd_process. [how] A svm_bo reference to amdgpu_amdkfd_fence to allow differentiate between SVM_BO or regular BO evictions. This also include modifications to set the reference at the fence creation call.
