Odroid-XU3: Add documentation for Odroid-XU3

Browse source 
This patch adds documentation for Odroid-XU3. This documentation is
based on that of Odroid (doc/README-odroid) made by Przemyslaw Marczak.
The documentation includes basic information about boot media layout,
environment, partition layout, and the instruction to burn the u-boot
image to boot media.

To prepare bootable media you need boot binaries provided by hardkernel.
File "boot.tar.gz" (link in point 3.) contains:

without problem)
