We get gpc_mask by calling GR HAL g->ops.gr.get_gpc_mask()
But gpc_mask should be logically owned by gr/config unit
Hence add new gpc_mask field to nvgpu_gr_config
Initialize it in nvgpu_gr_config_init() by calling a new HAL
g->ops.gr.config.get_gpc_mask() if available
If HAL is not defined we just initialize it based on gpc_count
Expose new API nvgpu_gr_config_get_gpc_mask() to get gpc_mask
and use this API now
Remove gr_gm20b_get_gpc_mask() and HAL g->ops.gr.get_gpc_mask()
Update GV100 and TU104 chip HALs to remove old and add new HAL
Add gpc_mask to struct tegra_vgpu_constants_params to support this
on vGPU. Also get gpc_mask from vGPU private data in
vgpu_gr_init_gr_config()

Unit gr/config right now queries gpc_count from priv_ring by directly
reading the value from register
priv_ring unit now exposes below HAL to get gpc_count
g->ops.priv_ring.get_gpc_count()
Use this HAL in gr/config unit

In gr/config unit we right now query max gpc_count and tpc_per_gpc_count
by directly accessing registers using hw_top_gm20b.h h/w header
Update TOP unit to provide below HALs
g->ops.top.get_gpc_count()
g->ops.top.get_tpc_per_gpc_count()
And call these HALs from gr/config

Add new unit gr/config to initialize GR configuration like GPC/TPC
count, MAX count and mask
Create new structure nvgpu_gr_config that stores all the configuration
and that is owned by the new unit
Move below fields from struct gr_gk20a to nvgpu_gr_config in gr/config.h
Struct gr_gk20a now only holds the pointer to struct nvgpu_gr_config
u32 max_gpc_count;
u32 max_tpc_per_gpc_count;
u32 max_zcull_per_gpc_count;
u32 max_tpc_count;
u32 gpc_count;
u32 tpc_count;
u32 ppc_count;
u32 zcb_count;
u32 pe_count_per_gpc;
u32 *gpc_tpc_count;
u32 *gpc_ppc_count;
u32 *gpc_zcb_count;
u32 *pes_tpc_count[GK20A_GR_MAX_PES_PER_GPC];
u32 *gpc_tpc_mask;
u32 *pes_tpc_mask[GK20A_GR_MAX_PES_PER_GPC];
u32 *gpc_skip_mask;
u8 *map_tiles;
u32 map_tile_count;
u32 map_row_offset;
Remove gr->sys_count since it was already no longer used
common/gr/config/gr_config.c unit now exposes the APIs to initialize
the configuration and also to query the configuration values
nvgpu_gr_config_init() is called to initialize GR configuration from
gr_gk20a_init_gr_config() and gr_gk20a_init_map_tiles() is simply
renamed as nvgpu_gr_config_init_map_tiles()
Expose new API nvgpu_gr_config_deinit() to deinit the configuration
Expose nvgpu_gr_config_get_*() APIs to query above configuration
fields stored in nvgpu_gr_config structure
Update vgpu_gr_init_gr_config() to initialize the configuration
from gr->config structure
Chip specific HALs that access GR register for initialization
are implemented in common/gr/config/gr_config_gm20b.c
Set these HALs for all GPUs
