gpu: nvgpu: rework ecc structure and sysfs

- create common file common/ecc.c which include common functions for add
  ecc counters and remove counters.
- common code will create a list of all counter which make it easier to
  iterate all counters.
- Add chip specific file for adding ecc counters.
- add linux specific file os/linux/ecc_sysfs.c to export counters to
  sysfs.
- remove obsolete code
- MISRA violation for using snprintf is not solved, tracking with
  jira NVGPU-859

Jira NVGPUT-115
