- 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.
