This patch does the following. 1. Remove unused functions from volt_pmu.c. 2. Append public functions with nvgpu. 3. Remove GP106 functions and rename TU104 to generic functions. 4. Rename volt struct from gpu_ops. 5. Remove the unused volt.h header file. 6. Make local functions as static and put in order. 7. Remove unused inclusion on header files. 8. After 4, generic functions can be called directly instead of g->ops.
