db7bb6548b gpu: nvgpu: remove clk_arb.h to gk20a.h circular dependency 
clk_arb.h and gk20a.h has circular dependencies to each other. This is
removed by forward declaring struct gk20a in clk_arb.h and removing the
header gk20a.h from clk_arb.h and similarly forward declaring struct
nvgpu_clk_arb in gk20a.h and removing the header clk_arb.h from gk20a.h
alongwith putting headers in every execution unit which calls clk_arb.h
related methods.

6c9daf7626 gpu: nvgpu: fix gpc_tpc_mask to use max_gpc_count 
gpc_tpc_mask uses gpc/tpc IDs directly read from fuse, so it needs to
use max_gpc_count for any possible cases rather not gpc_count.

26783b85bf gpu: nvpgu: Rename Linux specific vidmem code 
Rename os/linux/vidmem.c to os/linux/dmabuf_vidmem.c. The code is
mainly dealing with interfacing with Linux dmabuf framework and its
responsibilities got confused with common/mm/vidmem.c.

Also move the header include/nvgpu/linux/vidmem.h to
os/linux/dmabuf_vidmem.h. It does not expose any interface to outside
Linux code.

Move all Linux source code files to drivers/gpu/nvgpu/os/linux from
drivers/gpu/nvgpu/common/linux. This changes the meaning of common
