Subject: drm/amd/amdgpu: vcn10 Add callback for emit_reg_write_reg_wait
Git-commit: dfe8a0187c8dde66b3bc52882826b1e53920ad56
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The callback .emit_reg_write_reg_wait was missing for vcn decode
which resulted in a kernel oops.
