42ccc21c62 gpu: nvgpu: fix static violations in common
* Updated types and added error checks
 * Modified GR condition for ctxsw disable count
   CERT-C error check was added to detect error on integer overflow
   But below logic couldn't detect first overflow, so updated condition

   INT_MAX < gr->ctxsw_disable_count --> it became true after overflow
   So, we didn't detected in first overflow and lead to assert on enable

6dbf8e3d58 gpu: nvgpu: Remove unused code from common.top
Remove following error paths as they would never get called:
1. In gm20b_device_info_parse_enum:
   - This is a private HAL and is only called by get_device_info HAL.
   - It gets called only for table entry with entry type = enum.
   - So we remove the check if(entry_type != enum)...

2. In gp10b_device_info_parse_data:
   - This is a private HAL and is only called by get_device_info HAL.
   - It gets called only for table entry with entry type = data.
   - So we remove the check if(entry_type != data)...

3. In gp10b_get_device_info
   - entry corresponds to 2 bit extracted from the table_entry.
   - So, entry can have only 4 possible values.
   - We would never reach the else case; hence remove it.

Reduce the code complexity for gp10b_get_device_info() by creating a
helper function gp10_check_device_match().

This reduces the TCC metric from 14 to 9.

e53d24d6d2 gpu: nvgpu: fix MISRA Rule 8.6 violations
ifdef function prototypes with CONFIG_* defines. This fixes MISRA rule
8.6 violations which complain about undefined functions.
Also moved nvgpu_channel_get_from_file prototype to ioctl_channel.h &
nvgpu_probe to driver_common.h as those are linux specific. Define
nvgpu_init_soc_vars in posix/soc.c as it is implemented in QNX.

dependency hw_top_gxxxx.h from ltc unit is removed.

69ef86e627 gpu: nvgpu: move safe code HAL files to fusa
This patch moves all the safe static and non-static functions as well
as its dependencies such as static declared structs into files with
_fusa.c extension. If the original file is left with no functions
remaining then the file is deleted.

Added changes in Makefile, Makefile.sources, nvgpu-hal-new.yaml for
compilation.
