video: tegra: nvmap: Refactor nvmap_dev unit
...
- 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.

video: tegra: nvmap: Do not recycle handle id immediately
...
xa_alloc can return the handle id which was freed recently. Instead,
once handle id is provided, next time start from next handle id. Once
max limit is reached then start from U32MAX / 2 again.
