docs/uos: Deconditionalize, remove minor port-specific details. 

For a couple of ports, there was information which directory is set
as current after boot. This information doesn't belong to "uos" module,
and is moved to boards' references (which actually already contained
information on which directory is chosen for boot, even if without
explicit mentioning that it becomes current directory, which is now
done).

The filesystem has ``/`` as the root directory and the
available physical drives are accessible from here. They are currently:
``/flash`` -- the internal flash filesystem
``/sd`` -- the SD card (if it exists)

On boot up, the current directory is ``/flash`` if no SD card is inserted,
otherwise it is ``/sd``.
