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.
