rock-pi-e: add
Add support for Radxa's ROCK Pi E device https://wiki.radxa.com/RockpiE It's a great surprise to find upstream U-Boot and the Linux kernel already provide support for this board! On the kernel side this support was added in 5.11. However, that support is so new that even linux-yocto-dev (which is based on 5.11) doesn't include the commits that add support for this board yet. As a result I've added a custom Linux kernel recipe (linux-stable-bleeding) which should, in time, become unnecessary. Signed-off-by: Trevor Woerner <twoerner@gmail.com>
