On certain platforms, not all copy engine instances are usable. The user shouldn't submit any work to these engines. To enforce this, remove these engines from active/host_engine list, this should ensure that these engines do not get advertised to userspace. In order to accomplish this introduce the following functions: - nvgpu_engine_remove_one_dev: This function removes the specified device entry from following device lists: fifo->host_engines, fifo->active_engines, runlist->rl_dev_list, runlist->eng_bitmask. Replace iteration over LCE device type entries using nvgpu_device_for_each(g, dev, NVGPU_DEVTYPE_LCE), along with this introduce macro nvgpu_device_for_each_safe. Introduce gpu_dbg_ce flag for CE debugging.
