gpu: nvgpu: rename gk20a_locked_gmmu_map() and move to gmmu.h

Browse Source 
Rename the two native GPU GMMU map/unmap functions and update the
HAL initializations to reflect this:

  gk20a_locked_gmmu_map   -> nvgpu_gmmu_map_locked
  gk20a_locked_gmmu_unmap -> nvgpu_gmmu_unmap_locked

This matches what other units do for handling vGPU "HAL" indirection.

Also move the function declarations to <nvgpu/gmmu.h> since these are
shared among all non-vGPU chips. But since these are still technically
HAL operations they should never be called directly. This is a bit of
an organixational issue that I have not thought through hwo to solve
yet.

Ideally they would go into a "hal/mm/gmmu/" include somewhere, but
that A) doesn't yet exist, and B) those are chip specific; these
functions are native specific. Ugh.
