7f14aafc2c 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

d859c5f4a0 nvgpu: gv11b: Rearrange gr function
Moved gv11b_detect_ecc_enabled_units function
from gv11b.c to gr_gv11b.c, as this is being
used only in gr_gv11b file.

In order to avoid GR code touching fuse registers,
as it need to include fuse HW headers in GR code,
introduced two fuse HALs which are being called
from GR code. is_opt_ecc_enable for checking
whether ecc enable bit is set in fuse register
and is_opt_feature_overide_disable for checking
whether feature override disable bit is set in
fuse register.

Initialized fuse HAL functions for chips that
make use of those HAL functions.

ACR allocates buffers from vidmem and passes explicitly flag
NVGPU_DMA_NO_KERNEL_MAPPING. Vidmem buffers are never mapped to CPU,
and dGPU ACR does not actually care, so switch to using
nvgpu_alloc_vid_at(). This removes another explicit dependency
to NVGPU_DMA_NO_KERNEL_MAPPING, which is going to be removed.
