membar.sys does synchronization with the whole system (GPU and CPU),
membar.gl does synchronization within the GPU.
In gv11b, fb flush is generating membar.gl instead of membar.sys, which
is an issue. To fix this issue. following WAR is used:
1. Use bar1 engine id and bind it to a particular pdb,
2. Then instead of a fb_flush, issue a tlb invalidate of the bar1 pdb.
Now allocation of vm for bar1 instance block and bar1 binding is done
without check for bar1 support. Only bar1 register mapping is done
based on bar1 support enabled.

Add remove_gr_sys() op to gpu_ops to reverse steps
done in create_gr_sysfs().
Make gv11b_tegra_remove() specific to gv11b instead
to properly remove sysfs nodes. This also helps in
having gv11b specific remove steps.
Also, update platform remove function of dGPU i.e.
nvgpu_pci_tegra_remove() to remove sysfs nodes. This
adds parity with iGPU platform remove.

and optionally check host and FECS status to preempt pending load of
context not belonging to the calling channel on GR engine during context
switch.
This should be called immediately after a submit to decrease worst case
submit to start latency for high interleave channel.
There is less than 0.002% chance that the ioctl blocks up to couple
miliseconds due to race condition of FECS status changing while being read.
For GV11B it will always preempt pending load of unwanted context since
there is no chance that ioctl blocks due to race condition.

Ensure that the error value is propagated back to gk20a_gr_isr() correctly
