gpu: nvgpu: add remove_gr_sysfs gpu op

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.
