Sumit Singh 96ffe0c64d gpu: nvgpu: Fix gk20a shutdown issue ...

With CONFIG_PM_GENERIC_DOMAINS_OF enabled, device reboot
was getting hung while shutting-down gk20a. It was
happening because genpd_dev_pm_detach() was railgating
gk20a while other thread was still accessing it.

So, assigning NULL to dev->pm_domain->detach for gk20a,
so that genpd_dev_pm_detach() is not called during gk20a
shutdown, which will not railgate it.

This patch will be reverted once we have clean shutdown
for gk20a.
