Changes added to support "rmmod nvgpu" in dgpu simulation after gpu poweron. nvgpu_engine-wait_for_idle got stuck in busy mode for nvdec and nvec engines in simulation as simulation doesnt support timeout. These engines are not valid engines in nvgpu engine list. Add nvgpu_engine_check_valid_id before checking engine status. Simulation crash on accessing 0xb81604 top interrupt register. Add func_priv_cpu_intr_top__size_1_v() function to get the supported size than using default MAX_INTR_TOP_REGS. nvlink is not supprted in dgpu simulation. Avoid warning for -ENODEV return. Avoid register read following gpu power off completion.
