gpu: nvgpu: add hal to get the bar2 vm size

Browse Source 
On ga10b+ platforms, more VM space is needed to map various buffers
to bar2 vm. Engine method buffer is mapped for each pbdma and for
maximum supported TSGs this requires more than 32MB of space.
Also we need to consider fault buffer space and vab buffer
space requirement.
