Add interface definitions for the fifo_rd and fifo_wr interfaces
Using interface definitions makes it possible to group pins of a peripheral into a interface pins. This allows us to use connect_bd_intf_net to connect all pins of the interface instead of having to manually call connect_bd_net for each for the pins. Using interface pins also unclutters the connections in the Vivado block design view a bit. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>main
