common.cic unit is divided into common.cic.mon and common.cic.rm
based on rm and mon process split.
CIC-mon subunit includes the code which is utilized in critical
interrupt handling path like initialization, error detection and
error reporting path. CIC-rm subunit includes the code corresponding
to rest of interrupt handling(like collecting error debug data from
registers) and ISR status management (status of deferred interrupts).
Split the CIC APIs and data-members into above two subunits.

Update enable_priv_ring testcase to account for
new priv_ring init sequence. Updated test to
check for following three conditions:
- priv ring init passes.
- priv ring init times out waiting for command completion.
- priv ring init fails with enumerate command returning error.

Add a new Central Interrupt Controller(CIC) unit in common code.
The interrupt handling is done in a distributed manner currently.
The error handling policy for different errors resides in each unit's
ISR code. The goal is to converge this data under one central place -
the CIC unit.
This patch creates framework for CIC unit and moves the gv11b QNX
safety LUT to CIC unit. All the error reporting APIs from different
units are also moved to CIC.
New APIs are exposed by CIC unit to access its internal data like:
1. Struct err_desc - the static err handling /injection data per
error id
2. Num_hw_modules - the number of error reporting HW units
supported by CIC
Init and deinit of CIC unit:
1. CIC unit should be initialized earlyon during boot so that it
is available for any interrupt handling.
2. Initialize CIC just before the interrupts are enabled during
boot.
3. Similarly, CIC is disabled late during deinit cycle; right
after the interrupts are masked.
LUT:
1. LUT is currently used only for reporting error to safety
services in gv11b QNX safety build.
2. This error handling policy LUT currently has only two levels
of handing - correctable and quiecse.
3. Once, the error handling policy decision is moved from leaf
unit nodes to CIC, LUT will be updated to have additional levels
like fast recovery and full recovery.
4. Also, then a separate LUT will be added for each platform/build.
5. In current framework, the LUT is set to NULL for all
configurations except gv11b.
report_err() ops is added to report error to safety services.
This ops is only effective for gv11b qnx build; and set to NULL for
other configurations.

Many tests used various incarnations of the mock register framework.
This was based on a dump of gv11b registers. Tests that greatly
benefitted from having generally sane register values all rely
heavily on this framework.
However, every test essentially did their own thing. This was not
efficient and has caused a some issues in cleaning up the device and
host code.
Therefore introduce a much leaner and simplified register framework.
All unit tests now automatically get a good subset of the gv11b
registers auto-populated. As part of this also populate the HAL with
a nvgpu_detect_chip() call. Many tests can now _probably_ have all
their HAL init (except dummy HAL stuff) deleted. But this does
require a few fixups here and there to set HALs to NULL where tests
expect HALs to be NULL by default.
Where necessary HALs are cleared with a memset to prevent unwanted
code from executing.
Overall, this imposes a far smaller burden on tests to initialize
their environments.
Something to consider for the future, though, is how to handle
supporting multiple chips in the unit test world.
