video: tegra: nvmap: Refactor nvmap_dev unit

Browse Source 
- Add nvmap_dev.h file which include declaration for functions and data
structs which are exposed by nvmap_dev unit to other units.
- Also, add nvmap_dev_int.h file which include declaration for
functions which are internal to nvmap_dev unit that can be called by
files within nvmap_dev unit.
- Move definition of nvmap_handle_get_from_id, nvmap_install_fd,
find_range_of_handles to nvmap_handle.c as they belong to nvmap_handle
unit.
- Cleanup nvmap_priv.h by moving all relevant items for nvmap_dev unit
to nvmap_dev unit.
- Remove nvmap_mm.c file as nvmap_zap_handle is the only function
present; move it to nvmap_cache.c where it's being called.
- Remove function declarations whose definition are not present.
