This change solves crashes during bind that were introduced in the driver
during the OS unification refactoring due to lack of coverage of the remove()
function.
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
stopped

Move non-function pointer members out of the pmu and pmu_ver
substructs of gpu_ops. Ideally gpu_ops will have only function
ponters, better matching its intended purpose and improving
readability.
- g.ops.pmu_ver.cmd_id_zbc_table_update has been changed to
g.pmu_ver_cmd_id_zbc_table_update
