Seshendra Gadagottu 9e02111a76 gpu: nvgpu: fix race condition with poweroff 
When gpu rail-gating is enabled, it is possible that
both rail gating code and system shudown can start
executing gk20a_pm_prepare_poweroff() in parallel.
To synchronize this execution, protect gk20a_pm_prepare_poweroff()
with a mutex lock.

Bug 200168805
