Terje Bergstrom dd739fcb03 gpu: nvgpu: Remove gk20a_dbg* functions
Switch all logging to nvgpu_log*(). gk20a_dbg* macros are
intentionally left there because of use from other repositories.

Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages
are deleted.
