When flashing OBE ROM on PG189 with an internal chip SKU, it
ends up enumerating with unsupported device id. Since VBIOS
update will be done automatically in PDK, we want to detect
such boards, and throw a warning.
Use upper bits of driver_data to define some flags for pci device.
Added PCI_DEVICE_F_INTERNAL_CHIP_SKU for boards with internal
chip SKUs.
Allow enumeration of PG189 boards with internal chip SKUs

cyclestats_snapshot data and lock is right now stored in struct nvgpu_gr
Use case itself is not specific to GR engine but in general it applies
to other units outside of GR too.
Hence it makes sense to move both data and lock to struct gk20a instead
of keeping them in struct nvgpu_gr

gr_gk20a.ctx_vars struct right now stores sizes for golden_image, zcull,
pm_ctxsw, and gfxp_preemption_buffer.
but these sizes should be really owned by respective units and should
be assigned to units as soon as they are queried from FECS
Add new structure to nvgpu_gr_falcon to hold sizes that will be queried
from FECS
struct nvgpu_gr_falcon_query_sizes {
u32 golden_image_size;
u32 pm_ctxsw_image_size;
u32 preempt_image_size;
u32 zcull_image_size;
};
gr.falcon unit now queries sizes from FECS and fills this structure.
gr.falcon unit also exposes below APIs to query above sizes
u32 nvgpu_gr_falcon_get_golden_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_pm_ctxsw_image_size(struct nvgpu_gr_falcon *falcon);

u32 nvgpu_gr_falcon_get_zcull_image_size(struct nvgpu_gr_falcon *falcon);
gr.gr unit now calls into gr.falcon unit to initailize sizes, and then
uses above exposed APIs to set sizes into respective units
vGPU will too fill up struct nvgpu_gr_falcon_query_sizes with all the sizes
and then above APIs will be used to set sizes into respective units
All of above means size variables in gr_gk20a.ctx_vars struct are no more

several related fixes:
1. Move the cache code in gk20a/mm_gk20a.c and gv11b/mm_gv11b.c to
the new cache HAL. Update makefiles and header includes to take
this into account. Also rename gk20a_{read,write}l() to their

3. Update some direct calls to gk20a MM cache ops to pass through
the HAL instead.
4. Update the unit tests for various MM related things to use the

This change accomplishes two architecture design goals. Firstly it

Secondly it moves code from the gk20a/ and gv11b/ directories into
