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.

Work around this warning by simply moving the type punning.
This code is certainly dangerous - it assumes the endianness
of the header data is the same as the machine this code is
running on. Apparently it works, though, so this ignores
the warning.
