This function gets the GPU chip architecture, implementation and
revision information by reading the MC boot register, hence it
is more suited to be located in HAL files.
test_check_gpu_state is now being run after test_hal_init as the
gops.mc needs to be initialized for test_check_gpu_state subtest.

The two MM functions nvgpu_set_pd_level() and nvgpu_vm_do_free_entries()
are simple recursive functions for processing page descriptors (PDs) by
traversing the levels in the PDs. MISRA Rule 17.2 prohibits functions
calling themselves because "unless recursion is tightly controlled, it
is not possible to determine before execution what the worst-case stack
usage could be." So, this change limits the recursion depth of each of
these functions to the maximum number of page table levels by checking
the level against the MM HAL max_page_table_levels().
This also required configuring this HAL in various unit tests as they
were no previously using this HAL.

Until now, using single thread we disable the signal handler to
make it easier to debug crashes. Since we are now using single
threading in GVS, it is better to have the signal handler enabled
by default. This patch introduces a "-d" argument to explicitly
disable the signal handler and thus make local debugging easier.

For some units that depend on libraries, tmake generates
what seems to be stub libraries, with all functions
implemented as a simple 'ret' instruction.
For instance, libfalcon_utf.so can be seen in multiple places:
du -b $(sudo find . -name libfalcon_utf.so)
7808 ./nvidia/kernel/nvgpu/userspace/units/pmu-l4t_64/libfalcon_utf.so
7808 ./nvidia/kernel/nvgpu/userspace/units/acr-l4t_64/libfalcon_utf.so
7808 ./nvidia/kernel/nvgpu/userspace/units/falcon/falcon_tests-l4t_64/libfalcon_utf.so
76968 ./nvidia/kernel/nvgpu/userspace/units/falcon-l4t_64/libfalcon_utf.so
76968 ./systemimage/home/nvgpu_unit/units/libfalcon_utf.so
The "real" library is in falcon-l4t_64/, and it contains actual code.
But install-unit.sh copies all *.so files to nvgpu_unit/units on target.
In some cases, we end up with a "stub" library being used instead of
the expected one.
To avoid this, make sure to copy the largest libraries (in bytes) last.
Also, remove the '-u' option of rsync to force the copy.

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.

Modified gv11b_tsg_init_eng_method_buffers to inline computation
of method buffer size, as existing static function could never
return 0, making one branch not testable.
Added dummy IO register spaces for PFB, CE, PBUS and HSUB_COMMON,
so that g->ops.mm.init_mm_support can be called as part of
test_fifo_init_support. MM support is needed to test allocation
and mapping of DMA buffers.
