gpu: nvgpu: Reorg mm HAL initialization

Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch only covers the
mm sub-module of the gpu_ops struct.

Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.
