gpu: nvgpu: Update Linux side VM code for API solidification
Update the Linux specific code to match the MM API docs in the previous patch. The user passed page size is plumbed through the Linux VM mapping calls but is ultimately ignored once the core VM code is called. This will be handled in the next patch. This also adds some code to make the CDE page size picking happen semi-intelligently. In many cases the CDE buffers can be mapped with large pages.
