When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.
Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.
This allows us to by-pass debugfs initialization if debugfs
is not enabled.

1. Add tsec device entry in the DT overlay file
2. Copy over the existing tsec driver source code
and compile it when building with oot kernel
3. Add a dummy tsec folder with an empty Makefile
which conveys that common driver source is used
from kernel/nvidia/drivers/video/tegra/tsec

Add empty makefile and its path for building nvmap.
The source code and makefile with proper entries are
copied from the kernel/nvidia to out folder during build.
This will help to build the module for OOT from the source
code available in the kernel/nvidia which supports multiple
versions of kernel and avoid duplication of code.
