* gpu: nvgpu: Reorg misc HAL initializationSunny He2017-07-06
| | | | | | | | | | | | | | | | | Reorganize HAL initialization to remove inheritance and construct the gpu_ops struct at compile time. This patch covers the lone function pointers of the gpu_ops struct. Perform HAL function assignments in hal_gxxxx.c through the population of a chip-specific copy of gpu_ops.
