Deepak Nibade fc12a284bf gpu: nvgpu: initialize per GR instance config ...

Expose below two new APIs from common.grmgr unit
nvgpu_grmgr_get_gr_num_gpcs() - get per instance number of GPCs
nvgpu_grmgr_get_gr_gpc_phys_id() - get physical GPC id for MIG engine
local id in corresponding instance

Execute gr_init_config() for each GR instance.
Add gr_config_init_mig_gpcs() to initialize GPC data in case MIG is
enabled. Separate out gr_config_init_gpcs() for legacy GPC data
initialization.

These functions will inititialize below data in struct nvgpu_gr_config:
max_gpc_count
gpc_count
gpc_mask
gpc_tpc_mask[gpc_count]
max_tpc_per_gpc_count

Rest of the values in struct nvgpu_gr_config are either based on above
values, or read from HW after setting GPC PRI window.

In gr_config_alloc_struct_mem(), rename total_gpc_cnt to total_tpc_cnt
since it represents total TPC count and not GPC. Remove use of temp3
variable since it does not give any idea on usage.
