c6affb85ba gpu: nvgpu: unit: init: cleanup quiesce 
The init unit test starts the quiesce feature during testing. This
includes starting the quiesce thread. The thread should be stopped when
the init unit tests complete, so call nvgpu_sw_quiesce_remove_support()
when complete.

6c3c360462 gpu: nvgpu: protect nvgpu power state access using spinlock 
IRQs can get triggered during nvgpu power-on due to MMU fault, invalid
PRIV ring or bus access etc. Handlers for those IRQs can't access the
full state related to the IRQ unless nvgpu is fully powered on.

In order to let the IRQ handlers know about the nvgpu power-on state
gk20a.power_on_state variable has to be protected through spinlock
to avoid the deadlock due to usage of earlier power_lock mutex.

Further the IRQs need to be disabled on local CPU while updating the
power state variable hence use spin_lock_irqsave and spin_unlock_-
irqrestore APIs for protecting the access.

4a5ee02291 gpu: nvgpu: unit: init: update to work with new init design 
To address CCM in nvgpu_finalize_poweron(), some init APIs were updated
and broke the init unit test, so it was disabled. This addresses the
breakage and re-enables the test.
