[PATCH 1/2] i2c-designware-pci: Add Haswell ULT device IDs

[Benson Leung <bleung@chromium.org>]

From: Duncan Laurie <dlaurie@chromium.org>

Add the necessary PCI Device IDs to use the Haswell ULT
I2C controller in PCI mode.

Set the bus numbers to -1 so it will use dynamic assignment
rather than hardcoded.
