gk20a/hal.c depends on HAL init functions in all chips. But all chips also depend on gk20a. That creates a circular dependency. In order to solve the above, move gpu_init_hal and gk20a_detect_chip to common/init/hal_init.c. These methods are declared in include/nvgpu/hal_init.h. Also, the above methods are renamed to nvgpu_init_hal and nvgpu_detect_chip respectively.
