- struct nvgpu_falcon to hold properties of falcon controller - falcon controller interface layer which establish access to required falcon controller HAL based on struct nvgpu_falcon member flcn_id & flcn_base parameter. - each falcon nvgpu_falcon struct initialized during init with id, base-address along with other properties at HAL. - Added defines related to flacon controller.
