Remove Gr engine reset during ELPG entry.
Engine reset is causing clock gating logic to get reset thus
clock gating gets disabled during ELPG entry sequence.
It leads to higher power numbers observed at light graphics.
Removing GR reset during ELPG entry helped save power.

Also work around pointer munging warning:
/build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c: In function 'nvgpu_pmu_process_init_msg':
/build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c:348:4: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
(*(u32 *)gid_data.signature == PMU_SHA1_GID_SIGNATURE);
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.

PMU response(intr callback for messages) can run faster
than the kthread posting commands to PMU.
This causes the PMU message callback to skip important pmu
state change(which happens just after the PMU command is posted).
Solution:
State change should be triggered from only inside the intr callback.
Other places can only update the pmu_state variable.
This change also adds error check to print in case command post fails.

This change solves crashes during bind that were introduced in the driver

The fixes during remove are:
(1) Prevent NULL dereference on GPUs with secure boot
(2) Prevent NULL dereferences when fecs_trace is not enabled
(3) Added PRAMIN blocker during driver removal if HW is no longer accesible
(4) Prevent double free of debugfs nodes as they are handled on the
debugfs_remove_recursive() call
(5) quiesce() can now be called without checking is HW accesible flag is set
(6) added function to free irq so no IRQ association is left on the driver after
it is removed
(7) prevent NULL dereference on nvgpu_thread_stop() if the thread is already
