Deepak Nibade 4ab8c87974 gpu: nvgpu: expose V2 device node hierarchy

Nvgpu will move to new V2 device node hierarchy by default to be
consistent with MIG mode hierarchy. As part of this, expose V2 device
node hierarchy with this patch.

Both legacy and V2 hierarchies will co-exist for some duration until
V2 hierarchy is well tested out, and then legacy hierarchy will be
removed.

With V2 hierarchy, below is the directory structure for dev nodes :
igpu: /dev/nvgpu/igpu0/<dev_node>
dgpu: /dev/nvgpu/dgpu-0001\:01\:00.0/<dev_node>
