ARM: dts: aspeed: amd-ethanolx: Enable secondary LPC snooping address
AMD EthanolX CRB uses 2-byte POST codes which are sent to ports 0x80/0x81. Currently ASPEED controller snoops only 0x80 port and therefore captures only the lower byte of each POST code. Enable secondary LPC snooping address to capture the higher byte of POST codes.
