The EP108 was an early access development board that is no longer used. Add an info message to convert any users to the ZCU102 instead. On QEMU they are both identical. This patch also updated the qemu-doc.texi file to indicate that the EP108 has been deprecated. Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Emilio G.
