Add documentation of the xlat tables library V2
The documentation describes the design of the translation tables
library version 2 used by the ARM Trusted Firmware.
The diagram file has been created with Dia version 0.97.2. This tool
can be obtained from: https://wiki.gnome.org/Apps/Dia/Download
Inkscape has been used to generate the *.png file from the *.dia file
to work around a bug in the generation of *.png files in some versions
of Dia.
