ruby: route all packets through ruby port

Browse Source 
Currently, the interrupt controller in x86 is connected to the io bus
directly.  Therefore the packets between the io devices and the interrupt
controller do not go through ruby.  This patch changes ruby port so that
these packets arrive at the ruby port first, which then routes them to their
destination.  Note that the patch does not make these packets go through the
ruby network.  That would happen in a subsequent patch.
