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.
