ARM: dts: aspeed: Yosemite V2: Enable OCP debug card

Added IPMB-13 channel for Debug Card communication which improves the
readability of the machine and makes it easier to debug the server and
it will display some pieces of information about the server like "system
info", "Critical sensors" and "critical sel".
