Removed gr dependency on ecc by moving ecc init/remove support
calls to nvgpu_init. With this, only dependency from ecc to gr
present.
Added following parameter in struct nvgpu_ecc to check/update ecc
initialization status:
bool initialized;

Refactor the ECC code present under gp10b/, gv11b/, and tu104/. To
do this a few things were required:
Firstly, move the ecc related C and H files under the aforementioned
directories over to their new home under hal/gr/ecc/. Also copy over
the ECC HAL code present in gp10b/gp10b.c - not sure why this was
there but it, too, needed to be refactored. Also handle all the
updated header paths and Makefiles to take these movements into
account.
Secondly add a new HAL in GR (gr.ecc) to handle ECC HAL ops. There's
only two: detect and init. init() was copied over from gr and detect
was added so that the common ECC code can call it in a chip agnostic
way. This is required so that the ECC detect can be moved out of the
gp10b init characteristics function.
Lastly update the ECC init flow in the common ecc module to call
detect() right before init().

Moved cbc related code and data from gr to cbc unit.
Ltc and cbc related data is moved from gr header:
1. Ltc related data moved from gr_gk20a -> gk20a and it
will be moved eventually to ltc unit:
u32 slices_per_ltc;
u32 cacheline_size;
2. cbc data moved from gr_gk20a -> nvgpu_cbc
u32 compbit_backing_size;
u32 comptags_per_cacheline;
u32 gobs_per_comptagline_per_slice;
u32 max_comptag_lines;
struct gk20a_comptag_allocator comp_tags;
struct compbit_store_desc compbit_store;
3. Following config data moved gr_gk20a -> gk20a
u32 comptag_mem_deduct;
u32 max_comptag_mem;
These are part of initial config which should be available
during nvgpu_probe. So it can't be moved to nvgpu_cbc.
Modified code to use above updated data structures.
Removed cbc init sequence from gr and added in
common cbc unit. This sequence is getting called
from common nvgpu init code.

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

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.
Adding "U" at the end of the integer literals or casting operands
to have same type of operands when an arithmetic operation is

This fixes violations where an arithmetic operation is performed on
signed and unsigned int types.
