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.
