gpu: nvgpu: debugfs code to dump HAL functions

Browse Source 
Prints addresses of device-specific HAL functions to debugfs file
hal/gops.

The list of functions is produced by dumping the contents of the
gpu_ops substruct of the gk20a struct. This interface makes the
assumption that there are only function pointers in gpu_ops.

Companion Python script nvgpu_debug_hal.py analyzes gk20a.h to
determine operation counts and prettyify debugfs interface's
output.
