f73d035983 gpu: nvgpu: vgpu: add vgpu_css_init 
Added vgpu_css_init to setup ivm at init time.

Background:
vgpu_css_reserve_mempool was called at runtime in many places without any lock.
To avoid racing, the patch moves it to init time and rename it to vgpu_css_init.

1533951567 gpu: nvgpu: move cyclestats_snapshot data to struct gk20a 
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

Update all cyclestats_snapshot code to refer data/lock from struct gk20a
Remove gr_priv.h header include from cyclestats_snapshot.c

Some of the functions were mistakenly declared in gr_gk20a.h.
Move them to cyclestats_snapshot.h and rename them to form nvgpu_css_*()

vgpu_init_support in vgpu_linux.c
gk20a_init_support in module.c

Call gr free before the gk20a free call in nvgpu_free_gk20a.
