Documentation: move Trusty documentation to doc/

Browse Source 
Move the existing Trusty document to the doc/ folder (where
it belongs) and convert the text to ReST.

The Documentation/ folder under hypervisor/ is removed as all
documents should be put under doc/.

All technical information has been preserved or was already
available in other documents.
