gpu: nvgpu: Make "phys" nvgpu_mem impl

Browse Source 
Make a physical nvgpu_mem implementation in the common code. This
implementation assumes a single, contiguous, physical range. GMMU
mappability is provided by building a one entry SGT.

Since this is now "common" code the original Linux code has been
moved to commom/mm/nvgpu_mem.c.

Also fix the '__' prefix in the nvgpu_mem function. This is not
necessary as this function, although somewhat tricky, is expected
to be used by arbitrary users within the nvgpu driver.
