nvidia-t18x support

Steps to use this:

Set up vibrante installation, mine looks like this:
$ ls -l ~/VibranteSDK
total 234880
drwxrwxr-x 1 louai louai       298 Mar 20  2014 eclipse
-r-xr-xr-x 1 louai louai 171826846 Jan  4 09:59 NVIDIA_Tegra_Graphics_Debugger_2.1_linux-v4l_l4t-egl.run

drwxrwxr-x 1 louai louai       228 Jan  5 13:56 vibrante-t186ref-linux
drwxr-xr-x 1 louai louai       314 Feb 10 10:58 vibrante-t186ref-linux_sr

Set up Yocto build dir:
$ mkdir ~/work
$ cd ~/work
$ ~/tqtc-b2qt/yocto-meta/b2qt-init-build-env init --device tegra-t18x

Add NVIDIA's Yocto things:
$ mkdir ~/work/sources/nvidia-layer
$ cd ~/work/sources/nvidia-layer
$ tar xf ~/VibranteSDK/vibrante-t186ref-linux_src/yocto/nvidia-layer.tgz
$ cd -

Set up build environment:
$ export MACHINE=tegra-t18x
$ . setup-environment.sh

Set the following environment variables:
$ export KERN_DIR=~/VibranteSDK/vibrante-t186ref-linux_src/kernel
$ export PLATFORM_TOPDIR=~/VibranteSDK/vibrante-t186ref-linux
$ export TOOLCHAIN_PATH=~/VibranteSDK/toolchains/tegra-4.9-nv
$ export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE TOOLCHAIN_PATH KERN_DIR PLATFORM_TOPDIR"

Add NVLAYER_DIR to local.conf:
$ echo 'NVLAYER_DIR = "${TOPDIR}/../sources/nvidia-layer"' >> conf/local.conf

Build your image:
$ bitbake b2qt-embedded-qt5-image

Flash your board:

$ cd $PLATFORM_TOPDIR
$ mv targetfs targetfs-old
$ cd targetfs && tar xf /path/to/rootfs.tar.bz2
$ cd ../../vibrante-t186ref-foundation/utils/scripts/bootburn
$ ./bootburn.sh -b p2382-t186
