gpu: nvgpu: Begin removing variables in struct gk20a

Browse Source 
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.
