Alex Waterman 01c98eb680 gpu: nvgpu: VM map path refactoring ...

Final VM mapping refactoring. Move most of the logic in the VM
map path to the common/mm/vm.c code and use the generic APIs
previously implemented to deal with comptags and map caching.

This also updates the mapped_buffer struct to finally be free
of the Linux dma_buf and scatter gather table pointers. This
is replaced with the nvgpu_os_buffer struct.
