Get number of SMs from GR instance specific nvgpu_gr_config pointer
instead of global SM count in below functions :
nvgpu_gr_fs_state_init()
gv11b_gr_init_sm_id_config()
Update nvgpu_gr_config_get_gpc_skip_mask() to return 0 in case gpc_index
is greater than available gpc_count. This is not MIG specific, but based
on code review possible even today for existing chips.
See gm20b_gr_init_pd_skip_table_gpc()
Update nvgpu_gr_get_override_ecc_val() to return GR instance specific
value.
Execute gr_init_setup_hw() for each GR instance.
Disable below failing unit tests:
nvgpu_gr_fs_state.test_gr_fs_state_error_injection
nvgpu_gr_init.test_gr_init_hal_config_error_injection

Add new API nvgpu_grmgr_get_num_gr_instances() that returns number of
GR instance enumerated by GR manager. This just returns number of sys
pipes enabled since it is same as number of GR instances.
For consistency until common.gr supports multiple GR instances
completely, add a temporary macro NVGPU_GR_NUM_INSTANCES and set it
to 1. If this macro is changed to 0 (for local MIG testing), fall
back to use nvgpu_grmgr_get_num_gr_instances() to get enumerated number
of GR instances.
Use a for loop to initialize other variables of struct nvgpu_gr.
Remove unnecessary NULL check in nvgpu_gr_alloc() since struct gk20a
pointer can never be NULL in this path. Also remove corresponding unit
test code.

Overriding of ECC feature is used only in Linux through device
tree fuse overrides. It's not supported in QNX. Hence compile
out below functions from safety build.
nvgpu_gr_get_override_ecc_val()
nvgpu_gr_override_ecc_val()
Move nvgpu_gr_get_golden_image_ptr() under CONFIG_NVGPU_DEBUGGER
Re-arrange all functions in gr_utils.c/h and move all non-safe
functions towards end of file.
