Upgrade robots to the latest NWS/NWC layers - 4

[davidetome]

This PR modifies XML files for the following robots :

• iCubEdinburgh01
• iCubSingapore01
• iCubShenzhen01
• iCubHongKong01

The mods have been done starting from the default XML file contained in the yarprobotinterface.ini file (i.e. icub_all.xml)
The new files should be tested by the users.

@randaz81 , could you please have a look at them?

Tested all robots of this PR using DEBUG mode by adding these lines to the pc104.xml file :

    <group name="DEBUG">
        <param name="embBoardsConnected"> 0 </param>
    </group>

and setting in the general.xml file :

      <param name="skipCalibration">    true  </param>

This avoid yarprobotinterface terminating if not detects ETH boards; in this way, we test the correct parsing of the xml files.

Fixed errors on :

• iCubEdinburgh01
• iCubShenzhen01
