66a2511a36 gpu: nvgpu: Begin removing variables in struct gk20a
Begin removing all of the myriad flag variables in struct gk20a and
replace that with one API that checks for flags being enabled or
disabled. The API is as follows:

  bool nvgpu_is_enabled(struct gk20a *g, int flag);
  bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state);

These APIs allow many of the gk20a flags to be replaced by defines.
This makes flag usage consistent and saves a small amount of memory in
struct gk20a. Also it makes struct gk20a easier to read since there's
less clutter scattered through out.

b3e1ce04b9 gpu: nvgpu: Put debugfs dependencies inside #ifdef
Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This
includes some functions in allocators that were used only for
debugging.

Remove include of linux/debugfs.h on files that do not deal with
debugfs.

linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.

b928f10d37 gpu: nvgpu: Start re-organizing the HW headers
Reorganize the HW headers of gk20a. The headers are moved to a
new directory:

  include/nvgpu/hw/gk20a

And from the code are included like so:

  #include <nvgpu/hw/gk20a/hw_pwr_gk20a.h>

This is the first step in reorganizing all of the HW headers for
gm20b, gm206, etc. This is part of a larger effort to re-structure
and make the driver more readable and scalable.
