Remove the last sg_phys() call from the GMMU code and replace it
with a generic nvgpu_mem API. This new API, nvgpu_mem_get_phys_addr(),
returns the physical address of an nvgpu_mem struct.
Also, implement this new API in the Linux specific nvgpu_mem code
since it requires access to the underlying SGT/SGL.
