Move interrupt specific data-members from common.mc to common.cic
Some of these data members like sw_irq_stall_last_handled_cond need
To be initialized much earlier during the OS specific init/probe stage.
Also, some more members from struct nvgpu_interrupts(like stall_size,
stall_lines[]), which will soon be moved to CIC will also need to be
initialized early during the OS specific probe stage.
However, the chip specific LUT can only be initialized after the
hal_init stage where the HALs are all initialized.
Split the CIC init to accommodate the above initialization requirements.

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.

Replace all nvgpu_next functions/structs either by 1) collapsing them
into nvgpu legacy functions/structs 2) renaming them as follows:
- nvgpu_next_*() => nvgpu_(ga10b/ga100)_*()
- nvgpu_next_*() => (ga10b/ga100)_*()
- nvgpu_next_*() => nvgpu_*() [only if this doesn't cause collision]
- nvgpu_next_*() = > nvgpu_*_extra()
Create hal.sim unit and move Ampere+ SIM code into it.

CIC (Central Interrupt controller) will be responsible for the
interrupt handling. common.cic unit is the placeholder for all
interrupt related code. Move interrupt related defines and
Public APIs present in common.mc to common.cic.
Note: The common.mc interrupts related struct definitions are
not moved as part of this patch.
Adapt the code to use interrupt handling related defines and public

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.
