[PATCH 2/2] i2c: fix piix4 aux port number
From: Andrew Cooks
Date: Wed Nov 22 2017 - 22:10:14 EST
Let the aux port use port number one (not zero), to match the AMD
documentation and enable mapping ACPI _ADR to port number.
This fixes ACPI-based enumeration of I2C slave peripherals that are
defined for the aux SMBus port.
